Optical 3R regeneration with single InGaAsP/InP electroabsorption modulator

A new optical 3R regeneration technique, which is referred to as RF-XAM 3R regeneration, that requires only one electroabsorption modulator (EAM) for both clock recovery and gating was proposed for the first time. The idea was experimentally verified at 20 Gbit/s and we have confirmed that the RF-XAM 3R regenerator possesses retiming function. The simple configuration of our proposed scheme is expected to contribute not only to reduction in size and power consumption, but also high stability and easy tunability.
