Polarization Independent All Optical Clock Signal Extraction from NRZ Optical Signal

A novel structure of an all optical clock signal extraction circuit for NRZ signals is proposed. Polarization independent operation is achieved by the bi-directional use of a Mach-Zender interferometer for optical XOR operation. Applying the circuit to experiments where 40-Gbit/s NRZ signal is transmitted through 120-km SMF, the function of the proposed circuit is confirmed.
