Abstract
In this paper, a 60o waveguide bend is designed in a two-dimensional (2D) photonic crystal (PC) slab to provide high transmission over a large bandwidth. We apply geometrical modification in the bend region to improve the transmission characteristics. This modification results in increasing the relative bandwidth from 6.5% to 25.7% of PBG width. Using the effective refractive index, the structures are simulated by the 2D finite-difference me-domain (FDTD) method. As an application, we use the improved bend structure in a PC waveguide directional coupler and show that the drop output increases significantly.
