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 wavelength region.
