摘要： The present invention relates generally to semiconductor lasers and, more particularly, to schemes for measuring and controlling the temperature of semiconductor lasers and schemes for wavelength stabilization of semiconductor lasers. According to one embodiment of the present invention, a method of driving a temperature control mechanism (62, 64) in a semiconductor laser (10) is provided. According to the method, signals representing an operating temperature of the semiconductor laser and ambient temperature are generated and a target laser operating temperature that is a function of the ambient temperature signal is established. A temperature control mechanism of the semiconductor laser is then driven to increase a degree of correlation between the operating temperature signal and the target laser operating temperature.

摘要： A GRINSCH laser having an asymmetric configuration wherein the optical confinement is weighted more to the n-doped multilayer region than to the p-doped multilayer region. The GRINSCH laser can emit laser light at a wavelength λ = 976 nm over a broad area with a beam power of 11.4 W at a 12 A bias current and 20 o C heat sink temperature. Fabry-Perot and distributed Bragg reflector GRINSCH laser configurations are disclosed.
