Internet traffic is steadily increasing, and the transmission speed of optical communication is required to be further increased in order to transmit enormous traffic. At the same time, the services provided on the optical network are increasingly diversified. In particular, when the fifth generation mobile communication (5G) service is introduced, the diversification will continue to progress on the fusion network of the fixed and mobile ones.
In this laboratory, we are researching on the high-speed integrated circuits for optical transceiver, that can change their specifications flexibly to suit the various service requirements for the bit rate (time, wavelength, sub-carrier, and modulation format), power consumption and digital-signal processing delay.
