Abstract

The design, analysis, and simulation of a 1 × 2 decoder based on self-collimated beams was the aim of this work. The proposed structure consists of two-dimensional (2D) photonic crystals with their silicon rods in air. The device, of a relatively simple structure with a footprint of 228.71 μm², comprises two inputs (I and I_ref) and three outputs (Q₁, Q₂, and Q_I). It, furthermore, contains two beam splitters, produced by point defects. 2D Finite Difference Time Domain (FDTD) and Plane Wave Expansion (PWE) codes have been used for the simulation. Contrast ratio of 2.02 dB and a bit rate of 2.8 Tb/s were obtained for this device - potential candidate for all-optical digital integrated circuits.
