摘要

In this paper, a novel surface plasmon polariton based 2 x 1 multiplexer, which is based on an adder module and an all-optical controllable nano-plasmonic switching module is presented. It is shown that by applying a pump light, the transmissions of the input signals into the output waveguide can be controlled. The operation of the proposed device is investigated through the use of coupled-mode theory and finite-difference time-domain method. In the proposed adder module, the transmissions of the input signals at the working wavelengths are about 0.7. Based on the simulation results, by applying a pump light intensity of 150 KW/cm(2) the transmissions of input signals alter with the extinction ratio of 22.04 dB, which shows a significant switching effect. For a pump light intensity of 150 KW/cm(2) the switching times of input signals are measured about 560 fs. It is expected that the proposed 2 x 1 multiplexer can be used in all-optical signal processing, nano-plasmonic circuits, communication, etc.
