Abstract

A slab waveguide is made by spin coating a thin film of azopolymer onto a glass slide. A surface grating is then optically generated and acts as optical coupler. The structure exhibits resonance coupling as a function of the incident probe wavelength and angle of incidence. The transmission of the film is observed to decrease by more than 50 percent at resonance. The wavelength at resonance in seen to vary linearly with the angle of incidence for small angles.
