<title>Design Criteria For Integrated Optical Devices</title>

Abstract

Experimental results are presented and compared to theory for losses in Ti diffused LiNbO3 3μ wide channel waveguides having bends. The results include loss due to radiation of the energy away from the waveguide as it propagates around a curved portion of a wave-guide. Scattering loss at corner bends, straight to curved junction and curved to curved junctions are also presented. Experimental results of coherent coupling effects between successive abrupt bends to reduce bending losses is also presented.
