Spatial Profiling of Quantum Dot Lasers

This project involved a theoretical and experimental investigation of injection profiled semiconductor lasers containing self assembled quantum dot active regions for high brightness applications.

Semiconductor Quantum dots are nanostructures which display an intriguing blend of atomic and solid state properties. This project investigated the possibility of utilising these in novel for high power density semiconductor lasers.

Unique beam properties of these devices were experimentally discovered and explained using a nonlinear optical model based on the Maxwell-Bloch equations. These findings were reported in a number of journal publications.
