Design and analysis of photonic crystal ring resonator based 6 × 6 wavelength router for photonic integrated circuits

Abstract

A photonic crystal ring resonator‐based 6 × 6 router has been designed and reported. The router is designed using silicon pillars with a refractive index of 3.47 perforated in the air background of refractive index 1 in a square lattice with a lattice constant of a = 562 nm. The router is designed to operate in the third optical window wavelength which has low loss and most widely used in optical communication systems and networks. Plane‐wave expansion and finite difference time domain method has been used to obtain the bandgap and performance of the designed router, which exhibits acceptable performance such as low insertion loss, low propagation delay, and low crosstalk. These routers will find applications in the photonic integrated circuit that paves a path to all‐optical networks.

Design and analysis of Tbps all-optical gray code converter using photonic crystal-semiconductor optical amplifier-Mach–Zehnder interferometric structure

“…A photonic crystal (PhC) is an optical nanostructure made of well-ordered arrays of holes to confine and control the photon motion and strongly alter the dispersion relationship 1 – 3 In contrast, the conventional designs based on the nonlinearity of the semiconductor optical amplifier (SOA) are very attractive due to their strong nonlinearity, compactness, power efficiency, and integration possibility with different optoelectronic devices. Hence, combining the unique characteristics of SOA with novel PhC material justifies the use of PhC-SOA as a nonlinear element for designing all-optical devices for high-speed applications.…”

Investigation of the antenna characteristics with the impact of hexagonal metamaterial

“…MPA antenna plays a significant role in realizing all these applications, and it has more advantages 7–11 than other antennas. The MPA performances and limitations are enhanced by various methods like defected ground, metamaterials, 12,13 patched array, and photonic crystal 14,15 . This paper chooses the metamaterial concept and analyzes the antenna performances with the impact of these methods.…”

Design and performance analysis of eight channel demultiplexer using 2D photonic crystal with trapezium cavity

“…The PC can allow light into PBG by introducing a defect in the crystal or breaking the periodicity. The propagation of light in PBG enables the design of various components like fibre optics [10], filters [11], lasers [12], multiplexers [13], demultiplexer [14], Routers [15], logic gates [16], power splitters [17], and optical sensors [18] Wavelength Division Multiplexing (WDM) is an essential technology in optical communication systems. The WDM allows the single mode fibre (SMF) to carry a number of wavelengths per fibre.WDM is divided into Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM).…”
