Abstract

The coupling of a gaussian beam into thin films is investigated utilizing a full wave analysis. Maximum coupling efficiency for a planar structure is found to be 75% and is independent of the phase velocity of the waveguide mode in the film. Measured coupling values of up to 57% are reported. Coherence properties of the coupling procedure are discussed and optimization of physical parameters is outlined.
