1. Kiichi Hamamoto, Haisong Jiang, Mode selective active multimode interferometer laser diode - Mode selection principle, and high speed modulation, IEICE Transactions on Electronics, 10.1587/transele.2018ODI0003, E102C, 4, 364-370, 2019.04, We have proposed and demonstrated a mode selective active-MMI (multimode interferometer) laser diode as a mode selective light source so far. This laser diode features; 1) lasing at a selected space mode, and 2) high modulation bandwidth. Based on these, it is expected to enable high speed interconnection into future personal and mobile devices. In this paper, we explain the mode selection, and the high speed modulation principles. Then, we present our recent results concerning high speed frequency response of the fundamental and first order space modes..
2. B. Hong, T. Kitano, T. Mori, Haisong Jiang, K. Hamamoto, Bandwidth enhancement scheme demonstration on direct modulation active-MMI laser diode using multiple photon photon resonance, Applied Physics Letters, 10.1063/1.5005070, 111, 22, 2017.11, By introducing properly designed multiple photo photon resonances (PPRs) on an active-Multimode Interferometer Laser Diode, the confirmed direct modulation bandwidth was enhanced from less than 5 GHz to at least 34 GHz. Multiple oscillating cavities that have slightly different free space ranges (FSRs) are integrated within a single device. The overlap between such FSRs contributes to multiple wavelength differences that are directly related to the PPR frequencies. Evaluated PPR frequencies from experimental data match with designed frequencies. The potential of the 100 GHz level bandwidth of the device has been proved..
3. A. S. Idris, Haisong Jiang, Kiichi Hamamoto, Accurate dry etching technique for germanium waveguide by using CHF3 based inductively coupled plasma, Electronics Letters, 10.1049/el.2016.2846, 52, 22, 1868-1869, 2016.10, A CHF3 inductively coupled plasma (ICP) based dry etching method is proposed for accurate etching of Ge waveguides. CHF3 ICP based dry etching produces excellent anisotropy along with good selectivity with regards to regular polymeric photoresist, which leads to the elimination of under-cut. As a result, an almost vertical sidewall angle of 85° with an etching rate of 190 nm/min was realised with a relatively high selectivity ratio of 5:1 against regular photoresist..
4. Ryan Imansyah, Tatsushi Tanaka, Luke Himbele, Haisong Jiang, Kiichi Hamamoto, Electrically controlled optical-mode switch for fundamental mode and first order mode, Japanese Journal of Applied Physics, Part 1: Regular Papers & Short Notes, 10.7567/JJAP.55.08RB06, 55, 8, 2016.08, We have proposed an optical mode switch, the principle of which is based on the partial phase shift of injected light; therefore, one important issue is to clarify the proper design criteria for the mode combiner section. We focused on the bending radius of the S-bend waveguide issue that is connected to the multi mode waveguide in the Y-junction section that acts as mode combiner. Long radius leads to undesired mode coupling before the Y-junction section, whereas a short radius causes radiation loss. Thus, we simulated this mode combiner by the beam-propagation method to obtain the proper radius. In addition, we used a trench pin structure to simplify the fabrication process into a single-step dry-etching process. As a result, we successfully fabricated an optical-mode switch with the bending radius R = 610 m. It showed the successful electrical mode switching and the achieved mode crosstalk was approximately %10 dB for 1550nm wavelength with the injection current of 60mA (5.7 V)..

The two different propagation modes realize two different identical paths in a single active MMI cavity simultaneously, with sharing exactly same port at one facet side. This novel concept contributes to realize relatively large cross-gain saturation region between the two identical paths, which result in stable bi-stability even in a relatively compact device size. Implemented devices showed relatively low operation current of 100mA and sufficient hysteresis window of 8mA with the cavity length of only 550µm. High optical ON/OFF ratio of more than 15dB was also confirmed successfully..
