Optimization of Prism Coupling Efficiency for Surface Electromagnetic Wave Excitation in the Infrared
The Ir SEW Coupling Efficiency of a BaF2 Prism Has Been Determined for Various Gap Heights and Internal Angle Configurations, Utilizing the Two Prism Coupling Technique and a CO2 Laser. Samples Consisted of W Foil and Ni, Pt, and Cu Films Deposited on Glass Substrates by Electron Beam Deposition and Vacuum Evaporation. Optimum Prism Coupling Gap Heights Were Found to Occur for Each Metal. It Was Determined that Selection of the Proper Internal Prism Angle Increases Coupling Efficiency by a Factor of 3 over the Coupling Efficiency of the Right Angle Prism. © 1977 Optical Society of America.
