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