Abstract :
Summary form only given. In this paper, we demonstrate a polarization independent and contrast-ratio-enhancing wavelength shifting module, which consists of two polarization-dependent semiconductor optical amplifiers (SOAs). With proper polarization alignment, we perform 1 Gbit/s wavelength upshifting over 19 nm and reduce the power penalty for the shifter module from 5 dB to 1.5 dB and polarization dependence from 3.5 dB to 0.5 dB in comparison to a wavelength shifter compost of a single SOA.
