“…This eventually entails routing of signals between different ports in the integrated circuit networks with complete connectivity and improved performance [2]. Photonic crystalbased components such as splitters [3,4], circulators [5], filters [6], decoder [7], low-power encoders [8][9][10], and routers [11][12][13] were designed and reported. Among them, routers play a vital role in transmitting signals from one user to others with low loss and high efficiency in order to deliver high-quality signals to the end-users and minimise the traffic in the data transmission.…”

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.

Optical encoder is playing an essential starring role in optical communication and computing applications. This paper presents a new structure for 4 x 2 optical encoder based on Two Dimensional Photonic Crystals (2DPC). The proposed structure consists of silicon rods in background of air using hexagonal lattice. The proposed structure is composed of four input waveguides and two outputs. The band structure is examined by Plane Wave Expansion (PWE) method and the performance parameters of the 4x2 encoder, namely, normalized output power, footprint, contrast ratio, response time and bit rate are analyzed using Finite Difference Time Domain (FDTD) method. The proposed encoder is operated at 1550nm. The low response time, and small footprint have shown that the encoder is exceptionally suitable for high performance optical networks and photonic computational integrated devices.
