title: Use of a dielectric stack as a one-dimensional photonic crystal for wavelength demultiplexing by beam shifting.
abstract: We demonstrate the use of a 30-period dielectric stack structure as a highly dispersive device to spatially separate two beams with a 4-nm wavelength difference by more than their beam width. Unlike previous devices, our structure is simple to fabricate and relatively compact. We discuss possible applications of our device within wavelength-division multiplexing systems.
