Abstract

The use of a one-dimensional dielectric stack structure as a wavelength demultiplexer with angular dispersion many times higher than that of a conventional grating or prism is discussed. This 30-period device is based on the 'superprism' effect in photonic crystals. The experimental demonstration of the spatial separation of two beams with a 4-nm wavelength difference by a distance greater than their beam width is also highlighted.
