Abstract

The effect of sidewall roughness (SWR) on the performance of 1  2 optical power splitter is investigated. For the sake of simplicity, the SWR, assumed to take a periodic triangle shape, is considered in different sections of waveguide. The impact of SWR on the output power ratio is analyzed in detail. The corresponding insertion loss and power penalty due to SWR are determined using OptiBPM. Simulation results show that the output power decreases as the roughness increases due to increasing of scattering loss. Accordingly, the insertion loss and the power penalty increase and this would lead to degrade the output power in the corresponding waveguide branch and hence, the output power ratio deviates from the designed value..

Keywords
