Bianca E. Nelson, Martina Gerken, David A. B. Miller, Rafael Piestun, Chien-Chung Lin, and James S. Harris, Jr., "Use of a Dielectric Stack as a One-Dimensional Photonic Crystal for Wavelength Demultiplexing by Beam Shifting," Opt. Lett. 25, 1502-1504 (2000).

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.
