Optimized 1×4 Y Shaped Splitter for Integrated Optics

Abstract

In this paper we design a brick that will form the photonic crystals network. In particular, we focus on the optimization of a 1×4 Y-Shaped Splitter used for routing light exhibiting high transmission. A total transmission of about 88 % at output ports is obtained. Photonic crystals are considered a good way for realizing compact optical splitters. Propagation characteristics of proposed device are analyzed utilizing two-dimensional finite difference time domain (FDTD) method. The FDTD method will easily perceive the mechanisms involved in this device. The PhCs transmission properties are then presented and discussed.
