SOA-based regenerative amplification of phase noise degraded DPSK signals is demonstrated for a single and two non-demultiplexed channels. Q-factor improvement is 1.6 dB in the single channel and about 0.8 dB in the two channel regime.

We develop information-theoretical description of nonlinear optical communication systems. We present a non-perturbative calculation of the information capacity for different modulation formats, and demonstrate that fiber nonlinearity leads to exponential suppression of the channel capacity.

We describe a novel scheme for complete suppression of polarization-dependent loss/gain (PDL, PDG) for transmission-type optical devices (LPG, SOA) via a /spl lambda//2-shifted all-fiber Sagnac loop interferometer. The results are explained theoretically and demonstrated experimentally.

We investigate the nonlinear penalty of ultra-low-slope NZ-DSF with less than 50-/spl mu/m/sup 2/ effective area in nondispersion-compensated systems. For 80and 155-km, 10-Gbit/s transmission, negligible nonlinear penalty was found for launch powers up to 0 dBm/ch.

We demonstrate wavelength-shift-free 3R-regeneration of 40-Gbit/s optical RZ signal by OPA with a clock-modulated pump in highly-nonlinear fiber. The power penalty is improved by 2.6 dB, and the signal power is amplified by 7 dB.
