Patent ID: 7489873

Claim:
A monolithically integrated 3R regeneration system comprising: a first input port receiving a first split optical signal; a second input port receiving a second split optical signal, wherein the second input port is connected to a common input node; a first self-pulsating laser diode (SP 1 ) receiving either one of the first and second split optical signals and outputting a first regenerated clock signal; an interferometer monolithically integrated with the SP 1 , the interferometer receiving the first regenerated clock signal and either one of the first and second split optical signals and generating and producing a reshaped and reamplified output optical signal as a 3R regenerated optical signal, wherein the interferometer includes a first branch and a second branch each of which is connected to the common input node, such that the first regenerated clock or the second split optical signal is received by the common node and split to each of the first and second branch; and an output port outputting the 3R regenerated optical signal.
