Abstract

Bending loss of high-silica single-mode bending optical waveguides using a waveguide side-wall as a reflecting facet is described theoretically and experimentally as a function of the bending angle. Two types of bending waveguides, which have the reflecting facet exposed to the air coated with a metal film, are treated. The causes of bending loss are discussed in terms of los due to the Goos-Hanchen effect and the perpendicularity and roughness of the reflecting facet
