Abstract
In recent trend, the ultra-speed nanophotonics components are highly attractive for the scientific community and next-generation high-speed optical communication systems. In this present work, a novel four-port optical switch is proposed and designed using a two-dimensional photonic crystal platform. The proposed device is composed of waveguides and ring resonator in a square lattice with gallium phosphide rods arranged in an air medium. The plane wave expansion (PWE) method is used to identify the operating wavelength of the proposed device. The functional parameters of the optical switch such as normalized output power, bit rate, response time, extinction ratio, insertion loss, and crosstalk are analyzed using the finite-difference-time-domain method (FDTD). The presented platform is designed with the ultra-fast data rate of 6.52 Tbps, very low crosstalk of − 40.45 dB, and fast response time of 153.33 femtoseconds. Hence, it is tremendously suitable for high speed photonic integrated circuits and switching application.
