NONDESTRUCTIVE PROPAGATION LOSS AND FACET REFLECTANCE MEASUREMENTS OF GAAS/ALGAAS STRIP-LOADED WAVE-GUIDES

Abstract

A modified Fabry-Perot resonance technique using a single cavity was proposed to obtain the propagation loss of the optical waveguide. The propagation loss as well as the facet reflectance were measured without sequential cleavage for a GaAs/AlGaAs strip-loaded waveguide based on the contrast ratios of the reflected and transmitted interference patterns.
