Abstract
Optimized design of 60° bend optical waveguide has been proposed in this work. Two-dimensional (2D) triangular lattice Photonic Crystal (PhC) with holes in slab structure is used to design the waveguide having two 60° bends. A single hole in each of these bending regions is optimized to make the proposed design simple and easily fabricable. Plane Wave Expansion (PWE) algorithm has been used for evaluating the band diagram of the PhC. Finite Difference Time Domain (FDTD) method has been used to measure and analyze the wave propagation profile of the waveguide. Optical power transfer efficiency of the waveguide has been found as approximately 98% for two standard optical operating wavelengths.
