We investigated the effect of residual chromatic dispersion on phase-sensitive amplification of 20Gbaud 16QAM signals experimentally. We observed negligible impacts on amplification although the constellation is degraded in proportion to the amount of CD.
We experimentally demonstrate a tunable optical delay system that deploys dispersion, wavelength conversion In HNLF and multicasting in PPLN assisted with frequency comb lines pumping which offers discrete simultaneous access to the delayed signal.
We present a 2.3-Tbit/s network switching element by exploiting double-pass LCoS technology and bidirectional nonlinear effects inside a single HNLF. We demonstrate 2.3-Tbit/s grooming switch with simultaneous functions of add/drop, data exchange, and power equalization, for 23-channel 100-Gbit/s RZ-DQPSK signals.
