Abstract
The promise of photonic crystals was first formulated over 25 years ago, so it is time to assess what unique advantages these structures actually offer. I will look at a number of applications where photonic crystals have made an impact in order to highlight their unique features. The two main properties I will discuss are a) the ability to confine light in-plane, which includes cavities and slow light, and b) to control out-of plane radiation. The strong in-plane confinement gives rise to enhanced nonlinear effects, the Purcell factor, and efficient electro-optic modulation, while the control of out-of plane radiation is interesting for grating couplers, light emitting diodes, solar cells and biosensors.
