A spot-size transformer based on mode interference
Abstract
A novel mode-size transformer based on interference between guided and leaky modes is proposed and analyzed. Simulation shows significant improvement in spot-size transform efficiency per unit length, in comparison with the conventional tapered waveguide mode size converters based on mode evolution. Owing to its structural simplicity, easy fabrication is another merit of the new spot-size transformer.
