Photonic crystal heterostructure lasers

This presentation will discuss the use of photonic crystal heterostructure resonant cavities in microcavity lasers. The discussion of the experimental work will focus on the use of intermixing to reduce the optical losses in the photonic crystal mirrors, the demonstration of larger output powers, and an investigation of gain compression. The theoretical discussion will focus on cavity spectroscopy, the effect of the index of refraction of the substrate, and a calculation of the threshold gain in these devices.
