Using Photothermal Deflection Techniques for Studying the Attenuations of GuidedWaves Propagated in Optical Thin Films

摘要

A new experimental system, utilizing photothermal deflection techniques, doestest measurements of guided wave propagation attenuation in optical thin films. Lessons are drawn from propagation attenuation in wave guidance optics in order to characterize the losses and qualities associated with high quality optical thin films. Experimental results clearly show that attenuation coefficients are capable of very sensitively and completely reflecting thin film properties and quality. (AN).
