Simultaneous time- and wavelength-domain optical demultiplexing of NRZ signals by using a side-injection-light-controlled bistable laser diode
The authors have demonstrated direct optical demultiplexing of NRZ signals with simultaneous wavelength conversion by using a side-injection-light-controlled bistable laser diode module. The 250 Mbit/s demultiplexed output signals are each selected once every four bits from 1 Gbit/s NRZ optical input signals. Then each signal is regenerated and its bit width and wavelength are converted on one chip.
