Abstract

Optical multiplexing/demultiplexing with a narrow channel spectrum selectivity is an indispensable function in optical frequency division multiplication (FDM).1,2This paper reports the first verification of a narrowband active filtering using a DFB-type LD amplifier. The amplifying center frequency is selected by varying the bias current of the LD amplifier based on the carrier- dependent refractive index.
