Optical regenerator comprising a Kerr shutter

An optical regeneration system for regenerating a degenerated signal light, comprising a regeneration device having a Kerr shutter. The Kerr shutter comprises an optical LO (local oscillation) generator for generating an optical LO on an OPLL (optical phase locked loop), a phase comparator for detec...

Beschreibung
Zusammenfassung:	An optical regeneration system for regenerating a degenerated signal light, comprising a regeneration device having a Kerr shutter. The Kerr shutter comprises an optical LO (local oscillation) generator for generating an optical LO on an OPLL (optical phase locked loop), a phase comparator for detecting the phase difference between an externally-input signal light and an optical LO, and a control unit for regulating the repeated frequency of an optical LO based on the phase difference.
