Abstract:
We demonstrate an alternative DQPSK receiver offering reduced complexity through sharing of hardware in the I/Q demodulation paths. Demodulation of 43-Gb/s RZ-DQPSK is demonstrated without penalty relative to a traditional DQPSK receiver. Rate tuning is demonstrated through demodulation of a 21.5 Gb/s RZ-DQPSK signal with the same receiver structure.
