| Abstract: |
In this paper we will propose and design an all optical phase shift keying (PSK) demodulator using photonic crystal based coupled waveguides. The proposed structure should be designed such that it can generate digital 0 and 1 based on the phase of the input signal. The working mechanism is based on constructive and destructive of optical beams. 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 about 1.2 ps and 0.2 ps, respectively. [ABSTRACT FROM AUTHOR] |
