Patent ID: 8280261

Claim:
An Optical Signal Phase Regenerator characterized by processing two identical signals or mirrors, using Phase Shift Differential Modulation where two mirrors use: an amplitude modulator that has as its inlets an optical signal and an electric control signal, where the electrical signal is made up of a clock signal with a time greater than T/2, where T is the period of a symbol, and a temporary delay unit, wherein the optical signal is transmitted to an optical coupler, which in turn is connected to an optical temporary delay unit and to an optical signal phase shifter with a phase difference of 180°, subsequently passing through an optical coupler and an optical amplifier, wherein the outgoing signal from the optical amplifier is sent in turn through the optical fiber to the amplitude modulator and to a PIN photodetector the function of which is to convert the optical signal to an electrical signal, which passes through a level inverter, wherein the electrical signal is used to control the amplitude modulator through which the optical signal passes and this modulates the signal to remove the power transitory responses of the optical signal giving as a result an optical signal regenerated with phase shift differential modulation.
