Abstract :

Optical frequency shift keying demodulator is an optical structure that can generate logic 0 and 1 codes based on the frequency of the input signal. In this paper we proposed and designed a new structure for realizing frequency shift keying demodulator based on photonic crystals. The propose structure was designed using resonant cavities. The simulation results show that by setting the frequency of the input signal at 191 THz and 192.3 THz the proposed structure can generate log 0 and 1 bits. The rise time of the proposed structure is about 2 ps. Keywords: Optical Communications, Photonic crystal, FSK demodulator, Resonant cavity.
