Performance and design methodology of [Formula: see text] multiplexer (MUX) and all-optical reconfigurable logic circuit using GaAs–AlGaAs-based optical micro-ring resonator (OMRR) are presented in current paper. Proposed design of reconfigurable logic circuit is capable to perform eight different logic operations. Performances of the logic circuits have been theoretically analyzed using Z-domain modeling. Numerical simulation results confirming the method are explained in the present paper. Proposed circuit is simple, compact, efficient as it have minimum number of OMRR, low operating power, high operating speed and high Q-factor. Different ‘figure of merits’ of the purposed model are calculated from the simulation results.

In this paper we will propose and design an all optical amplitude shift keying demodulator using a photonic crystal based nonlinear ring resonator. The proposed structure will be designed such that it can generate digital 0 and 1 based on the amplitude of the input signal. The working mechanism is based on controlling the optical behavior of the resonant ring using optical intensity. The proposed structure was simulated using plane wave expansion and finite difference time domain methods. The simulation results show that the rise and fall times for the proposed structure are 0.5 and 0.1 ps, respectively.

AbstractIn this paper, ultra-fast, compact and high contrast ratio all optical half subtractor based on photonic crystal designed and simulated. The proposed design will be constructed using both threshold switching and interference of beams mechanisms. The proposed structure is composed of six waveguides and a nonlinear ring resonator. The simulation results show that the contrast ratio for D and B ports were obtained about 18.80 and 15.05 dB, respectively. Also the maximum rise, fall and steady-state times and total footprint for suggested all optical half subtractor are 0.5, 0.25, 1.5 ps and 234 μm2, respectively.
