Structures with periodically modulated refractive index are frequently discussed under the classification of photonic crystals. Recently, much attention has been paid to these types of structures for a large variety of applications such as the inhibition or enhancement of spontaneous emission, ultra-low threshold lasers, compact optical circuits, light-emitting diodes with increased efficiency and novel optical waveguides. Using structures that exhibit a photonic bandgap (PBG), it has been shown that high-Q, small modal volume microcavities can be created. Advances in semiconductor fabrication technology have made it possible to make semiconductor PBG microcavities for optical wavelengths.
