Optical Demultiplexing in a Planar Waveguide with
Colloidal Crystal
Ivan Avrutsky, Vladimir Kochergin, and Yang Zhao, Member, IEEE
Abstract--We report the first experimental demonstration of
demultiplexing capabilities of a 2-D waveguide grating consisting
of a monolayer colloidal crystal deposited on a top of a planar
waveguide. Self-assembled periodical structure with hexagonal
symmetry is formed by crystallization of polystyrene colloidal
particles. The experiments are performed in the 1550-nm wave-
length region.
Index Terms--Gratings, photonic crystal, waveguide, wave-
length-division multiplexing.
WAVELENGTH-division multiplexing (WDM) is a key
technology in modern optical communication systems,
that provides high communication bandwidth, utilizing a
wide range of the optical spectrum. Although a number of
WDM networks are already implemented, there is demand
for new approaches and new technologies that would provide
inexpensive and reliable solutions for WDM devices. Wave-
