In this paper a new structure was designed for realizing an all optical amplitude shift keying demodulator. Firstly a nonlinear optical demultiplexer was designed using four nonlinear resonant cavities, which were created by adding doped glass rods inside the cavity. Then the final structure was created by properly connecting the end sides of the output waveguides of the nonlinear demultiplexer. When the optical intensity of the input signal is 1, 2, 3 and 4 W/m2 the proposed structure can generate 00, 01, 10 and 11 codes at the output ports. The structure has maximum delay time of 11 ps..
