- 초록
- An apparatus for compensating a polarization mode dispersion including a polarization adjusting means for adjusting polarization states of an optical beam having a differential group delay based on a polarization adjusting feedback control signal; a polarization beam splitting means for splitting principal states of polarization of the adjusted optical beam into a first polarization and a second polarization; a time delaying means for the first polarization based on a time delay feedback control signal; a polarization adjustment controlling means for controlling the polarization adjusting means based on a polarization adjusting feedback control signal; a time delay controlling means for controlling the time delaying means based on a time delay controlling feedback signal; and an electric combining means for combining a time-compensated first polarization and the second polarization transmitted through the optical tap.
