Feasibility demonstration of 1.3/1.5 mu m amplifier-free transmission link at 10 Gb/s using two-mode injection locked laser diode as low-cost all-optical 2R regenerator

Abstract

This study presents amplifier-free all-optical 2R regeneration schemes based on a compact self-seeded Fabry-Perot laser diode (SSFP-LD) at 1.5 mu m and a two-mode injection locked distributed feedback laser diode (TMIL DFB-LD) at 1.3 mu m, respectively. The proposed 2R regenerator achieve straight line transmissions at 10 Gb/s over 60/76 km at 13/1.5 mu m without any traditionally required optical amplifier. In addition, the amplified gain and regeneration performance is experimentally investigated.
