Abstract Nowadays, the development of optical telecommunication systems requires more efficient all-optical elements appreciation to their high data transmission speeds and reduced electromagnetic interferences. In this work, our objective is to attest by simulation a design of an optical switch using 2D photonic crystals from polystyrene, an organic polymeric material with high Kerr non-linearity. This excellent ultra-fast switching leads us to the exploited in the construction of two new structures of all-optical AND/NAND and OR/NOR logic gates. These structures based on non-linear ring resonator NRR of different radius in order to operate a telecom wavelength of 1550.3 µm using RSoft (Full-Wave) software. The average contrast intensity is between 15.52 and 23.42 dB and low delay time varied from 20 fs to 5.0 ps. Hence, resulting a very high output signal for ON-switching (82–130% of P in) and a weak signal for OFF-switching (0.2–7% of P in) through a minimum threshold power around of 1.2 mW/μm2.

Abstract All optical logic gates are building blocks for all optical data processors. One way of designing optical logic gates is using threshold switching which can be realized by combining an optical resonator with nonlinear Kerr effect. In this paper we showed that a novel structure consisting of nonlinear photonic crystal ring resonator which can be used for realizing optical NAND/NOR and majority gates. The delay time of the proposed NAND/NOR and majority gates are 2.5 ps and 1.5 ps respectively. Finite difference time domain and plane wave expansion methods were used for simulating the proposed optical logic gates. The total footprint of the proposed structure is about 988 μm2.

A novel design of microring resonator called all-pass Mobius ring resonator is used to study optical bistability effect and spectral transmission for all-optical switching application with clockwise hysteresis loop operation. The bright soliton pulse is applied as the input source of the system. The propagation of the pulses within the system is simulated using the transfer matrix analysis. The all-pass Mobius ring resonator is able to operate under high nonlinearity as it has longer propagation length per roundtrip. The all-pass Mobius provides low transmission peak power of 3.65 mW as compared to the conventional all-pass configuration. The output-to-input relation of both design shows that the Mobius configuration is able to generate a higher hysteresis loop width of the bistable signal from 15.79 mW to 18.10 mW input power. The switching power of the optical bistability in Mobius configuration is 3.67 mW for threshold power of 16.95mW. This work shows the Mobius configuration is more suitable to be used for all-optical switching application as compared to the conventional all-pass ring resonator configuration.

The realization of all-optical polarization switch and all-optical logic gates based on polarization-conversion on single silicon micro-ring resonator (MRR) is demonstrated. By adjusting the mode state of the input source as well as the pump light, the all-optical polarization switch, and hence, all-optical NOT, OR/NOR. AND-NAND logic gates are realized. The design is ultra-compact, ultrafast, and less optical power is required for all-optical polarization-conversion-based switch and logic gates, respectively. The MRR also shows outstanding performance as its Q (quality) factor is very high. The design is robust, simple, stable, easy-to-fabricate, and silicon-on-insulator (SOI) compatible. The structure is compatible for interconnects and capable for integrating in electronics as well as in plasmonics circuits.

AbstractIn this paper, an ultra-fast all-optical modulator, based on a new shape of nonlinear photonic crystal ring resonator, is designed and studied. Numerical methods such as plane wave expansion (PWE) and finite-difference time domain (FDTD) are used to perform simulations. The modulation technique consists of carrier light controlling by means of input light signal and Kerr effect. The investigation of extinction ratio and insertion loss within the carrier input power shows that the choice of 0.7 W is the optimal value of that power to ensure the tradeoff between both characteristics. The suggested modulator demonstrates an excellent extinction ratio about 20.8018, a very low insertion loss of −13.98 and a short switching time about 13.4 ps. According to the obtained results, the modulator can be considered as an ultra-fast and ultra-compact optical component.

AbstractNonlinear photonic crystal ring resonators are suitable mechanisms that can be used for designing optical logic gates and digital structures. In this paper, we designed two nonlinear resonant rings by adding doped glass rods inside the photonic crystal ring resonator. An optical half adder was designed using these nonlinear photonic crystal ring resonators. We used plane wave expansion and finite difference time domain methods to simulate our optical half adder. The simulations show that when one of the input ports is ON, the normalized optical power at the S is about 90 %. The time delay in this case is 7 ps. Also when both the input ports are ON, the normalized optical power at the C is about 155 %. The time delay in this case is 8 ps.
