Abstract :
An ultra compact integrated silicon receiver for differential quadrature phase shift keying signals based on two tunable silicon-on-insulator microring resonators and four integrated germanium photodetectors is demonstrated. The device is experimentally characterized and the receiver operation is reported for signals ranging from 10 to 20 GBd.
