Paper Abstract

Distributed Bragg reflector (DBR) tapered lasers emitting near 1180 nm were developed. The integration of DBR surface gratings in an edge-emitting laser structure with a highly strained quantum well and a tapered laser geometry allows nearly diffraction limited emission into a single longitudinal mode with an optical output power of more than 2 W. The laser will allow direct second harmonic generation (SHG) in a single pass configuration and hence will enable the manufacturing of miniaturized laser modules near 590 nm for out-of-the-lab applications. An integration of a heater element at the DBR grating allows the tuning of the emission wavelength of more than 2 nm without the mechanical movement of gratings. This easy tuning simplifies the phase matching to a SHG crystal.
