Resonant Diffractive Optical Elements and their Applications

Resonance coupling effects in diffractive waveguides have applications in fields such as optical filtering and laser technology. These resonance effects arise on phase matching of an incident laser beam to a leaky waveguide mode. This presentation addresses theoretical modeling, experimental realization, and applications of this so-called guided-mode resonance (GMR) effect. Experimental results agree well with theoretical calculations. In particular, double-layer resonant reflection filters have been designed and fabricated and found to exhibit an experimental efficiency of 98% at 860 nm wavelength measured with a tunable laser at normal incidence.
