In this paper, we have investigated and
stimulated a two channel demultiplexer based on
plasmonics metal-insulator-metal (MIM) waveguide.
The metal used is silver (Ag) and insulating material is
air respectively. The proposed structure is
numerically analyzed by using the two dimensional (2-
D) finite difference time domains (FDTD) method.
Here the crosstalk and the quality factor are
measured. The minimum value of crosstalk measured
is -14.36dB and the maximum value of quality factor
is 56.81
