Sammanfattning : This thesis deals with the fabrication and characterization of grating-based integration-compatible semiconductor lasers. Waveguide gratings provide feedback for the laser resonators, and are used to diffract the laser output out of the waveguide for surface-emission. LÄS MER
4. Grating-Coupled Surface-Emitters --- Highly Directional Outcouplers and Spatially Coherent Lasers
Sammanfattning : This thesis deals with grating-coupled surface-emitting semiconductor lasers. The work is part of a larger effort that aims at developing semiconductor lasers with built-in beam-forming elements, which eliminate the need for external micro-optics. LÄS MER
