Abstract
A system and method include forming an optical cavity by positioning a photonic crystal a predetermined distance from a substrate, and creating, within the cavity, a standing wave having a substantially flat wavefront. The standing wave may be created by applying an input wave to a first surface of the photonic crystal. The predetermined distance may be such that a peak intensity of the standing wave is proximate to or a calculated distance from the substrate surface. The peak intensity may vary in relation to the substrate surface. The method may include tuning the peak intensity location within the cavity by shifting the wavelength of the input wave or altering the characteristics of the photonic crystal by an external field. A second photonic crystal may be used on the other side of the substrate to replace the reflecting properties of the substrate, allowing for further smoothing of the wavefront.
