Analysis of a proposed extension to the Fabry–Perot technique for measurements of loss in semiconductor optical waveguides

Abstract

A recent paper by Clark and Iqbal [Opt. Lett. 15, 1291 (1990)] proposed a novel modification of the conventional Fabry–Perot technique for measuring losses in semiconductor optical waveguides, which they claim eliminates the need for any knowledge of the reflectivities of the waveguide end facets. We show that the range of validity of this technique is quite limited and in many situations may be difficult to verify.
