Abstract
The 3R regeneration system for a retiming, reshaping, and reamplifying an optical signal includes: first and second input ports in which a connected optical signal is input; an interferometer including first and second branches formed on a substrate, split at a common input node, combined at a common output node, semiconductor optical amplifiers in each of the first and second branches, the first branch being connected to the first input port, and the common input node being connected to the second input port; a self-pulsating laser diode monolithically integrated with the interferometer between one of the first input port and the first branch, and the second input port and the common input node on the substrate, receiving an optical signal, and outputting the optical signal regenerated by optical injection locking; and an output port connected to the common output node.
