摘要：

In this work, a numerical analysis of a compact 1 x 2 plasmonic demultiplexer based on a metal-insulator-metal (MIM) waveguide is presented. Two hollow circular cavities are side coupled to the bus waveguide on both sides. The cavities are designed in such a way that they resonate at the working wavelength of 1310 nm and 1550 nm. The mechanism of light coupling to an MIM waveguide has not been considered in previous studies. Therefore, a silicon tapered mode converter is integrated with a plasmonic demultiplexer for the efficient conversion of a dielectric to a plasmonic mode. The footprint of the device is 6 mu m x 6 mu m. The crosstalk at P1 and P2 is similar to 14.07 dB and similar to 13.67 dB for the transmission wavelength of 1310 nm and 1550 nm, respectively.
