Y. Dong et al., Noninverted wavelength conversion with signal improvement and chirp compression utilizing birefringence in SOAs, OPT COMMUN, 191(3-6), 2001, pp. 229-234
By exploiting signal-induced birefringence in semiconductor optical amplifi
er, noninverted wavelength conversion for 10 Gb/s nonreturn-to-zero data wi
th enhanced extinction ratio(> 13 dB) and negative chirp (similar to5 GHz)
was obtained. Zero power penalty transmission over 110 km standard single m
ode fiber without any dispersion compensation after conversion was achieved
