Optimization of Curved Waveguide Design to Reduce Transmission Losses

Abstract: 

A waveguide designed to minimize bend-induced losses. The waveguide has three regions of varying indices of refraction. The indices of refraction are chosen so that the field is a trigonometric function in the core region, evanescent in the intermediate region, and trigonometric again in the outer region. The widths of each region are calculated to further reduce losses.
