Description
Summary:Optical frequency-selective amplification of an injected optical signal in a distributed feedback type semiconductor laser amplifier is studied. Based on this mechanism an optical demultiplexer with optical gain for optical frequency-division multiplexing is developed. A 9 GHz spectrum selectivity and a 11 dB extinction ratio are observed.
