Paper Abstract

Light can interact with periodic microstructures, also known as photonic crystals, in many ways. In this talk we will consider the use of photonic crystals to modify the wavefront and wavevector direction of waves propagating in photonic crystal slab waveguides and will compare these effects with those at arise from modification of the Poynting vector. We will discuss the underlying principles and will consider applications of these devices, in particular for wavelength demultiplexing. We will illustrate our investigation by considering the design of 1-D and 2-D photonic crystal superprism demultiplexers, and show that compact (<4 mm chip size) and high resolution (100 GHz) multichannel devices can be obtained.
