Abstract
In this paper, we designed a 2×2 optical switch using a two- dimensional photonic crystal (2D PC) based on interference principle. For the first time, an air-hole slab-structure-based photonic switch is proposed. The proposed optical switch consists of input and output bus waveguides connected by an open-corner parallelogram-shaped cavity that effectively controls light flow using interference. The propagation of electromagnetic waves is analysed using the finite-difference time-domain (FDTD) method. The proposed photonic crystal switch exhibits an ultrafast response time of 1.27 ps, supporting a data rate of up to 0.78 Tbps, with maximum crosstalk of −5.79 dB for cross state and -27 dB for bar state. Hence, the proposed photonic switch is suitable for high-speed switching applications.
