Profile
Rresearch focuses on the interdisciplinary field of molecular and polymeric materials with particular emphasis on high technology electro-optic and photonic materials and emphasis on novel photonic polymer device construction technologies. After careful control of molecular design and synthesis, research result dealts with high-performance topics including electro-optic ultra-fast switching, solid-state polymer laser, and polymer photonic crystals for low power operation. Though these polymer materials and optical devices have been considered as a future technology, it is becoming important recently because materials can provide much easier processing capability with promising properties compared with inorganic processes. Research is employed to approach “molecular engineering” to tailor size, shape, sequence, and functionality of organic and polymeric materials and explore their applications to:
・Electro-optic polymers for high-speed communications technology
・Polymer solid-state photonics device
・Fabrication of nano-micro scale polymer optical structures
To complements these efforts, research maintain state-of-the-art research fields in materials chemistry, photonics, and polymer nanao-micro scale manufacturing.

We introduce an innovative channel estimation technique, in-phase and quadrature separation pulse compression noise rejection (IQS-PCNR), for intensity modulation and direct detection (IMDD) optical orthogonal frequency division multiplexing (OFDM) systems. IQS-PCNR uses pulse compression to estimate the channel impulse response (CIR) and employs a noise rejection window to mitigate residual noise, resulting in significant performance improvements. Experimental results show that IQS-PCNR outperforms conventional methods, such as least squares (LS) and intra-symbol frequency-domain averaging (ISFA), while preserving comparable complexity. Specifically, IQS-PCNR provides a 2.87 dB and 0.61 dB enhancement in optical receiver sensitivity, along with a 3.65 Gbps and 1.85 Gbps increase in achievable bitrate at the hard-decision forward error correction (HD-FEC) threshold of 3.8 × 10<sup>−3</sup>, after transmission over a 2-km standard single-mode fiber (SSMF) link, compared to LS and ISFA, respectively. Additionally, IQS-PCNR enables the generation of real pilot signals with greater hardware efficiency.

Optical orthogonal chirp division multiplexing with chirp index modulation

We propose and experimentally demonstrate a modulation technique, termed orthogonal chirp division multiplexing with chirp index modulation (OCDM-CIM), where partial chirps are deliberately unmodulated to reduce interference and energy consumption. OCDM-CIM exhibits the combined advantages of interference rejection from the chirp-spread spectrum in OCDM and energy efficiency (EE) from index modulation, achieving an attractive trade-off among spectral efficiency (SE), EE, and performance by flexibly controlling the number of active chirps per subblock to adapt to different granularity requirements of the system. In addition, a distributed subblocking strategy is introduced to obtain additional coding and diversity gains. Experimental results show that compared to conventional orthogonal frequency division multiplexing (OFDM) with subcarrier index modulation under the same index parameter setting, the proposed OCDM-CIM reduces the peak-to-average power ratio by 2.5 dB at the complementary cumulative distribution function of 10−3, enhances optical receiver sensitivity by 2.7 dB, and increases the achievable bitrate by 8.7 Gbps at the bit error rate threshold of 3.8 × 10−3 for hard-decision forward error correction. Moreover, an improvement of 25% in EE can be achieved compared to OCDM at the same SE.

Flexible and compact optical switch is important for optical communications. In this Letter, a thermo-optical switch with wavelength division (de)multiplexing (WDM) function has been proposed and demonstrated experimentally. The switch is comprised of a 1 × 2 Bezier multimode interferometer (MMI) and an angled multimode interferometer (AMMI). The switch separates 1490 and 1550 nm wavelengths and realizes path reconfiguration simultaneously. The demonstrated device with a footprint of 13.63 × 0.385 mm2 is built on a 2% refractive index difference silica platform. The excess loss is lower than 1.2 dB (the reference waveguide loss is larger than 5.6 dB). In the central wavelength, the cross talk is lower than −21.7 dB and the extinction ratio is larger than 21.7 dB. The 3 dB bandwidth is larger than 30.8 nm. The wavelength shift rates of central wavelength are ∼54 pm/nm in C band and ∼74.8 pm/nm in the S band with the width of the AMMI changed. The rise (10%-90%) and fall (90%-10%) times of the switch are 0.88 and 0.94 ms, respectively, with a maximum power consumption of 246.6 mW. The demonstrated switch combines WDM and router functions together. Scalability property makes it possible for a large port count number switch.

Mode-division multiplexing (MDM) technology is promising for enhancing the capacity of communication networks. In this Letter, we demonstrate a dual-mode 2 × 2 electro-optical switch on a silicon-on-insulator platform. The dual-mode Mach–Zehnder interferometer switch comprises of four p-i-n phase shifters and two mode-insensitive multimode interferences that can be used for TE0 and TE1, simultaneously. With π/2 phase shifters introduced, push–pull like operation enables the power consumption lower than 2.15 mW. The average insertion loss of the switch in “cross” and “bar” states are 1.31 dB ± 0.19 dB for the TE0 mode and 3.39 dB ± 0.16 dB for the TE1 mode, respectively. The cross talk is less than −16.47 dB in the C band. The compact dual-mode switch is promising to conduct a large-scale, flexible MDM system on chip.

The gap between the performance of optoelectronic components and the demands of fiber-optic communications has narrowed significantly in recent decades. Yet, the expansion of data communications traffic remains substantial, with fiber-link speeds increases anticipated in the near future. Here, we demonstrate an ultra-high-speed electro-optic waveguide modulator constructed using a thin film of lanthanum-modified lead zirconate titanate with a ferroelectric phase exhibiting a strong Pockels effect. The modulator has a wide optical window; thus, the modulation was demonstrated for 1550 and 1310 nm wavelengths. This device showed electro-optical intensity signaling with line rates of 172 Gbit s−1, in conjunction with on–off keying modulation; this performance could be increased to 304 Gbit s−1 using four-level pulse modulation. The signaling performance of this modulator was found to be robust, with stable performance at temperatures as high as 100 °C. This technology is expected to have applications in a wide range of classical optoelectronic devices and in quantum science and technology.

We present a silicon slot microring resonator for efficient frequency conversion via four-wave mixing (FWM). The slot consists of a narrow silicon waveguide pair with a gap of 80 nm, which is filled with a nonlinear optical polymer. The group velocity dispersion for the microring is controlled by engineering the geometry of the slot structure. Because of the large buildup factor of the slot microring, an FWM conversion efficiency of −27.4 dB is achieved with an optical pump power of less than 1.0 mW. From the measured power dependence of FWM generation, a nonlinear refractive index coefficient of 1.31 × 10−17 m2 W−1 is obtained at a wavelength of 1562 nm. This work presents a hybrid silicon slot and polymer microring as a potential nonlinear device for applications in integrated photonic devices.

Integrated lithium niobate (LN) electro-optic (EO) modulators are emerging for applications in next-generation optical fiber communication
networks. To date, LN crystal waveguides have led the technology for high-speed modulators. On the other hand, on-chip LN modulators are
expected to realize scalable signaling devices with mature complementary metal–oxide–semiconductor technology. In this study, a siliconloaded LN modulator on the insulator substrate featuring a small footprint, a low driving voltage, and high-speed EO modulation is designed
and fabricated. No etching or patterning of the LN is required. The measured halfwave-voltage length product is 1.9 V cm with a static modulation extinction ratio of 17.9 dB. The fabricated LN modulator has a modulation bandwidth of 60 GHz and supports high-speed signaling at a data rate up to 200 Gbit/s.DOI： 10.1063/5.0109251

Efficient electro-optic (EO) modulation can be generated in the hybrid silicon modulator with EO polymer in the form of an in-plane coplanar waveguide and electrode structure. Strong confinement of the optical field in the hybrid structure is critical to performing efficient electric poling and modulation of the EO polymer. The waveguide consists of silica-based side claddings and an EO core for increasing the integral of the optical field and the overlap interaction between the optical field and the modulated electric field within the EO polymer. We discuss in detail the volume resistivity dependence of the efficiency of electric poling and modulation for various side-cladding materials. In a Mach-Zehnder interferometer modulator, the measured half-wave-voltage length product (VπL) is 1.9 V·cm at an optical communication wavelength of 1,550 nm under the TE optical mode operation. The high-speed signaling of the device is demonstrated by generating on-off-keying transmission at signal rates up to 52 Gbit/s with a Q factor of 6.1 at a drive voltage of 2.0 Vpp

With the technological advances such as the cloud computing and the rapid growth of use of Internet services, the information communication technology sector, especially datacentres, is experiencing an exponential increase in the energy consumption and hence a greater cooling challenge. One of the possible approaches to reduce the energy consumption in the datacentres is increasing the ambient temperature. However, it puts forward more stringent requirements for the reliability and durability of the optoelectronic components equipped in the datacentres at high ambient temperature. Herein, we fabricate and demonstrate silicon-polymer hybrid (SPH) modulators which feature an excellent reliability with an excellent signal fidelity retained at temperature up to 110 oC without deploying any energy-consuming temperature stabilization units, and meanwhile support single-lane data rates beyond 100 gigabits per second (up to 200 gigabits per second) with an electro-optic bandwidth of 68 GHz even after a long-period exposure to high temperature (100 hours, 90 oC). This is achieved by taking advantages of the high electro-optic (EO) activities (in-device EO figure of merit: n3r33=1021 pm V-1), low dielectric constant, and high glass transition temperature (Tg, 172 oC) of the developed side-chain EO polymers on a silicon substrate. Our high-temperature-resistant SPH modulator simultaneously fulfils the requirements on the bandwidth, EO efficiency and thermal stability for EO modulators. It could provide high-speed interconnects for energy-hungry applications such as data communication, effectively addressing the energy consumption issue for the next-generation optical communication networks. Moreover, it could also implement reliable interconnects for applications in harsh environment such as 5G, autonomous driving, LiDAR and aviation spacecraft systems.

In this study, we fabricated a polymer hybrid modulator using silicon waveguide, which consists of a traveling wave type electrode for highly efficient optical signal generation. The measured results of the modulation demonstrated symbol rate of 100 Gbaud and signal transmission of 200 Gbit/s. In experiments of the optical signal transmission, the signal error rate was analyzed as below the error-free accuracy, and it was confirmed that the signal transmission did not degrade even when subjected to temperature up to 110°C. As the goal of this research, a high-speed optical modulation device was fabricated and its highly efficient optical modulation performance was demonstrated.
