ABSTRACT:
An optical amplification device includes a depolarizer for reducing the polarization sensitivity requirements on an SOA by changing the input to the SOA from having an arbitrary (unknown) polarization state to a known (depolarized) state. The depolarizer receives an input optical signal and outputs a depolarized, optical signal, and a semiconductor optical amplifier (SOA) receives the depolarized optical signal and outputs an amplified optical signal.
