Abstract:
1. An apparatus for optical regeneration comprising: a first coupler for dividing an incoming degraded optical phase modulated signal into a first and a second degraded optical signal; an optical pump source connected to a first arm of said first coupler for receiving said first degraded optical signal, wherein said optical pump source is locked to the phase of said first degraded optical signal and generated a pump output; a first synchronization circuit connected to a second arm of said first coupler for receiving said second degraded optical signal and synchronizing said second degraded optical signal with said pump output, said first synchronization circuit comprises: a first coupling device for combining said pump output and said synchronized second degraded optical signal into a third and a fourth optical signal; and a first interferometer for receiving said third and said fourth optical signal to generate a phase regenerated signal, wherein said first interferometer includes a nonlinear optical material to provide phase regeneration of said incoming degraded optical phase modulated signal.
