【 摘 要 】

By utilizing cross-phase modulation and birefringence, we demonstrated simultaneous polarization-insensitive phase-transmultiplexing and multicasting of a single 10-Gbaud CSRZ-OOK signal and 4 × 10-Gbaud RZ-BPSK signals to generate 4 × 10-Gbaud RZ-QPSK signals in a photonic crystal fiber. The measured receiver sensitivity OSNR penalty at BER of 10^-9 was ≈1.8 dB, relative to the FPGA-precoded RZ-DQPSK baseline, for a randomly polarized CSRZ-OOK signal, when the launch angles of all RZ-BPSK signals were fixed at ≈ 45^°. In addition, the OSNR of the remotely generated CSRZ-OOK signal could be degraded down to ≈34 dB/0.1 nm, before the BER performance of the phase-transmultiplexing and multicasting operation began to degrade.
