Abstract

The present disclosure relates to a tunable laser module including a light gain area unit for outputting an optical signal; an optical distributor for separating the optical signal output from the light gain area unit; two comb reflection units for reflecting a part of optical signals separated by the optical distributor and allow a part of the optical signals to penetrate; two phase units for changing phases of the optical signals penetrating the two comb reflection units; an optical coupler for combining the optical signals of which the phases are changed by the two phase units; and an optical amplifier for amplifying the optical signal combined by the optical coupler, wherein the light gain area unit oscillates a laser by totally reflecting the optical signals reflected by the two comb reflection units.

First claim

What is claimed is:

1. A tunable laser module, comprising:
a light gain area unit configured to output an optical signal;
an optical distributor configured to separate the optical signal output from the light gain area unit;
two comb reflection units configured to reflect a part of optical signals separated by the optical distributor and allow a part of the optical signals to penetrate;
two phase units configured to change phases of the optical signals penetrating the two co…
