摘要：

An all-optical compact polarization T splitter based on 2-dimensional photonic crystal with uniform structural and bandgap characteristics is proposed in this paper. A square lattice of silicon substrate with embedded air holes is used to create the proposed structure. Linear waveguides with 90◦ bends are created for light propagation by removing a number of holes to build the structure. Plane Wave Expansion (PWE) and Finite Difference Time Domain (FDTD) methods are employed for simulating the structure. The transmittance of transverse electric (TE) polarized mode at 1550 nm is 96%. The structural parameters, such as air hole radius and dielectric constant, are homogeneous throughout the structure, making production easier and reducing fabrication errors. The proposed polarization splitter has a simple design with small footprints and high Q factor to meet the demands of current optical integrated circuits. © 2023, Electromagnetics Academy.
