Abstract
Vertical cavity lasers have been demonstrated with low thresholds and high efficiency. Wafer level testing is possible and packaging is simpler with excellent coupling to optical fibers. Two dimensional arrays of these lasers offer a new set of applications for semiconductor lasers. The design and properties of vertical cavity lasers are significantly different from in-plane lasers and present difficult theoretical design and analysis problems. Three important examples will be discussed here: Coupling between waveguides and DBR reflectors, relaxation oscillation dynamics, and chirping of vertical cavity laser output.
