The design and operation of integrated dual-wavelength sources are reported. These InGaAs-GaAs ridge waveguide (RW) distributed Bragg reflector (DBR) lasers consist of a common gain section and two, separate DBR sections. Multiple current injection is not necessary for these lasers to operate in dual-wavelength. Dual-wavelength operation is easily achieved by simply biasing the gain section. A relatively low coupling coefficient in the front grating reduces the added cavity loss for the backdoi:10.1109/68.883812 fatcat:35bnmk75yjh63km5q2lg4ef56i
