Abstract :
An optical demultiplexer based on the multimode interference (MMI) coupler is demonstrated in this work. The proposed device is designed and simulated by showing the optimum parameters for the structure (length of MMI region, the separation and the angle of the arm). The calculated results show that the crosstalk of the coupler is about -19.4 and -11.66 dB for 1310 and 1550 nm respectively. The insertion Loss is around 1.5-2.5 dB for demultiplexing operation.
