Two-dimensional colloidal crystal corrugated waveguides

Received February 24, 1999
We demonstrate, for what is to our knowledge the first time, two-dimensional (2D) corrugated waveguides at
optical wavelengths obtained by use of 2D colloidal crystals. We report experimental studies of light coupling
into and out of the waveguide structure. The diffracted light shows interesting optical properties that exist
only in such 2D grating structures. Field distribution of the fundamental mode in the structure is studied
by use of a simplified model in our analysis. Potential applications of this type of structure are discussed.
