Abstract

In this letter, the transmission efficiency around waveguide bend on the surface of photonic crystal is investigated. Light is confined to the photonic crystal-air interface by means of surface modes. The transmission efficiency around surface waveguide bend is shown to be very poor. This is due to the phase mismatch of the wave vectors between different sections of the surface waveguide bend. To reduce the phase mismatch between the different waveguide sections, the cell properties at the bend section are modified. As a result, high transmission efficiency of more than 93% around the modified surface waveguide bend structure is achieved.
