Paper Abstract

Photonic crystal membrane microcavities (PCMC) exhibit modes with highest quality factors and ultrasmall volume at the same time. This makes them the ideal solid state implementation for studying cavity quantum electrodynamics, as a quantum emitter such as a quantum dot can be placed at an electric field maximum with only moderate technological effort. Ultimately, this shall lead to novel classes of light emitters, such as highe efficiency LEDs or devices for quantum information processing. This paper discusses PCMC's operating in the weak coupling regime, shows an efficient and realistic simulation method based on the finite element method, and the design trade-offs for cavities used as light emitters. Finally, a comparison to measured spectra illustrates technological aspects.
