Abstract :
A fast mode-conversion evolution and wide-angle low-loss abrupt bent waveguide with apexes-linked microprisms is proposed and compared with the conventional single prism structure. For the proposed bent waveguide with bend angle 10/spl deg/, the transmitted power efficiency of 96.06% and a mode-conversion length of 40 μm can be achieved.
