All‐optical logic AND gate is realized based on two dimensional photonic crystal composed of Si rods in air. The structure proposed is designed with T‐junction using line defect and point defect in the crystal. Plane‐wave expansion and finite difference time domain methods are used to simulate and analyze the performance of the proposed AND gate. The size of the logic gate is only about 18 µm x 18 µm and it works in the 1550 nm wavelength. The contrast ratio obtained for this structure is 11db. The band diagram obtained for this structure gives a good forbidden band gap in the normalized frequency range of 0.264783 ≤ (1/λ) ≤ 0.4213565 for transverse electric mode. Therefore, band gap width is 0.1247972. The simplicity and the small sized T‐shaped structure along with high contrast ratio make this device suitable candidate for integration in optical communication.

In this paper, optical properties of one dimensional ternary metamaterial photonic crystal structures are studied. This structure is composed as (ENG/dielectric/MNG)N with N number of layers. This paper numerically studies the transmission behavior of one dimensional ternary metamaterial structure by using well known transfer matrix method. The transmission characteristics of such structure are examined with variation of refractive index and thickness of dielectric layer. Hence, the present study supports the potential application for tunable filter applications.

“…Basically, PC structure is designed with point defects and line defect to get the photonic band gap (PBG) and these structures could be in the form of 1-Dimensional, 2-Dimensional and 3-Dimensional where, 2-Dimensional PC is highly attractive due to the small size, high operating speed, low loss [2]. Based on 2D PC various devices has been designed such as optical waveguides [4,5], optical sensors [6][7][8], optical filters [9,10], multiplexer/demultiplexer [11][12][13], logic gates [14][15], optical switches [16][17], etc. The optical encoders can be designed with three different techniques as self-collimation [18], nonlinear effect [19][20] and interference effect [21][22][23][24].…”

In the present work, a high-speed optical encoder is proposed based on two-dimensional photonic crystal ring resonator (2D-PCRR) using coupled mode theory and resonance effect. Square shaped ring resonator, couplings rods and several waveguides have been utilized in the proposed structure. Silicon rods in air structure has been designed with rod radius of 0.1a and lattice constant 0.540 nm. The photonic band gap is being calculated using plane wave expansion method and finite-difference-time-domain method to analyze the performance characteristics of optical encoder like: transmission spectra, electric field view, contrast ratio, delay time, response time etc. The operating wavelength of structure is 1550 nm, to perform encoder operation where only one input port is activated at a time while other input ports are inactivated and accordingly equivalent binary encoded signal is produced at output ports. The proposed encoder is designed with fast response time 222.76 fs, high data rate of 4.48 Tbps and ultra-compact size of 140.84µm2. Hence the proposed device is suitable for high-speed optical computation, photonic integrated devices and high speed optical integrated circuits.
