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.
