Abstract

We use the two dimensional finite element method (2D-FEM) in the frequency domain to characterize the transmission properties of 900-bend periodic segmented waveguides (PSWs). We investigated the dependence of the transmission coefficient and the mode profile of PSWs on the bending radius, the waveguide duty cycle, and the operating wavelength. We show that 900-bend PSWs can be designed in photonic integrated circuits with a curvature radius as small as three times the wavelength to achieve transmission coefficient greater than 0.8
