Nanophotonics and Integrated Optics - Photonic Crystal Cavities

This whitepaper gives a general overview on different concepts of photonic crystal cavities. Important figures such as the transmission, the mode volume and the quality factor are discussed. The presented information will help the reader to decide which type of photonic crystal cavities will be most suited for the application in view. A design example for a WDM channel filter is given in order to illustrate the design process for a photonic crystal cavity. Furthermore two experimental examples from recent research are shown to demonstrate the wide range of applications in which photonic crystal cavities could be used.
