Paper Abstract

We present a novel design of an 1 x 2 photonic crystal beam splitter using silicon-on-insulator integrated optical technology. According to the design, we can reduce the size of beam splitter without increasing the propagation loss. In this paper, we study the 1x2 beam splitting ratio by changing the position of the center air hole. We use a finite-difference-time-domain (FDTD) method to simulate the propagation of the light. The 1x2 PBG beam splitter is designed with 180 degree output bending angles. The size of this novel beam splitting device are 8 μm x 3.44 μm.
