Abstract
Provided is a reflective colorless optical transmitter receiving a carrier signal, which is a continuous wave, and outputting a modulated optical signal. The reflective colorless optical transmitter includes a semiconductor optical amplifier (SOA) amplifying an input optical signal allowing the input optical signal to have a gain, an optical modulator connected to the SOA and outputting a modulated optical signal, a high reflectivity facet reflecting the modulated optical signal from the optical modulator, and a Bragg reflection mirror connected to the high reflectivity facet, the optical modulator, and the SOA in series, wherein a Bragg resonator is formed by the Bragg reflecting mirror and the high reflectivity facet.
