Abstract: PURPOSE: A tunable laser module is provided to improve an output characteristic by using two arms of a Mach-Zehnder light modulator for two output terminals. CONSTITUTION: A tunable laser module comprises a light gain area unit (401), a light distribution unit (402), a light coupling unit (407), and a light amplifying unit (408). The light distribution unit separates a light signal which is output from a light gain area unit. Two comb reflection units (403, 404) reflect one part of the light signal which is separated by the light distribution unit, and transmits the other part of the separated signal. The light coupling unit combines light signals whose phases are changed by two phase units (405, 406). The light amplifying unit amplifies the light signal which is combined by the light coupling unit. The light gain area unit oscillates laser by totally reflecting the light signal which are reflected by the two comb reflection unit.
