Abstract
- Design of the optical devices is an important matter of discussion in the present scenario where optical devices have become ultra‐compact due to miniaturization, ultra‐speed with the integration of optoelectronic devices. In this paper a 1 × 3 2D photonic crystal based on optical beam‐splitter has been designed on OptiFDTD for TE polarized light. The wafer is of the dimensions of 21 µm × 15 µm in length and width, respectively. The design works at the wavelength of 1.55 µm, and the mode is selected to be the Gaussian Modulated Continuous Wave (GMCW). The design is based on the 2D Hexagonal lattice, where the elliptical Si‐rods are placed in the air. This splitter prototype consists of one input and three outputs with the split ratio as 60:20:20. This refers to the first output port has 60% power of the transmitted signal, and the second and the third output ports have 20% power of the input. The structure is implemented using OptiFDTD software. It utilizes Finite Domain Time Difference (FDTD) numerical method to analyze the transmission spectra of the structure, and the Plane Wave Expansion (PWE) method is utilized to calculate the photonic bandgap of the prototype.
