Abstract

The efficient use of chip area in integrated optical circuits, and the displacement of waveguides to facilitate the coupling of such circuits to optical fibers requires transmission around bends, possibly utilizing etched mirror [2] or curved sections [3][4][5]. Because of distortions of the optical field that occur when guided waves travel through a curved section of an optical waveguide, radiation loss can be greatly increased. In fact, the minimum allowable radius of curvature of a waveguide is generally limited by radiation losses rather than by fabrication tolerances. Since waveguide bends are necessary part of all but the simplest Optical Integrated Circuits the radiation losses from a curved waveguide must be considered in circuit design.
