Abstract :
Optical feedback-tolerance of distributed-reflector (DR) laser with a wirelike distributed-feedback section and distributed-Bragg-reflector (DBR) section was investigated. Isolator-free 2.5-Gb/s-10-km transmissions and low RIN were demonstrated under -13.5-dB optical back-reflection with a power penalty of 2-dB.
