Abstract :
We present an optically-controlled tunable silicon DQPSK demodulator using optical force. It employs a cantilever nanostring to adjust phase shift by a counter-propagating control light. 40-Gbaud/s DQPSK demodulation is implemented using the designed opto-mechanical tunable DQPSK demodulator with the performance evaluated by Q-factor and BER.
