Optical communication systems laboratory Laboratory

In our 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.
Furthermore, the optical burst-mode transmission technique is also investigated to be applied the elastic transceiver to the optical access services. A new circuit configuration that makes flexibility without a degradation of the instantaneous response will be examined. In addition, a circuit configuration that allows flexible selection of the combination of the bit rate and power consumption according to traffic conditions while maintaining the fairness between users will be studied.
