Polarization mode dispersion compensating device using optical XOR circuit

摘要

A polarization mode dispersion compensating device is formed by a polarization mode dispersion equalizer, a polarization component splitting unit for splitting apart of the polarization mode dispersion compensated optical signal into the TE polarization component and the TM polarization component, an optical XOR circuit for carrying out an optical XOR operation on the TE polarization component and the TM polarization component, and a control system for controlling the polarization mode dispersion equalizer such that the logical operation result outputted by the optical XOR circuit becomes "0".
