Abstract
A wavelength tunable laser includes a first facet including a high reflection coating film; a gain region disposed adjacent to the first facet, the gain region including two or more light emitting devices that are arranged parallel to one another; an optical wavelength multiplexer optically connected to the light emitting devices; and an optical reflector disposed adjacent to a second facet opposite the first facet, the optical reflector having a reflection spectrum with periodic reflection peaks. The optical wavelength multiplexer is disposed between the gain region and the optical reflector, and the optical reflector and the first facet including the high reflection coating film form a laser cavity.
