“…In last decades it has been shown that photonic crystals (PhCs) [1,2] which consist of regular arrangement of dielectric materials with periodic refractive indices can be very useful for designing different kinds of optical devices [3][4][5]. The realization of optical filters [6][7][8][9][10], demultiplexers [11][12][13][14][15][16], logic gates [17][18][19][20][21][22], coders [23][24][25][26][27][28][29], adders [30][31][32][33][34][35] and analog to digital converters [36][37][38][39][40] proves the ability of photonic crystals for playing a crucial role in the next generation of all optical networks. An all optical phase shift keying (PSK) demodulator was designed using 2D PhCs [41].…”

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.
