Abstract
En 中文
The integer-programming model is established for designing a plasmonic demultiplexer. The plasmonic demultiplexers are composed of a ring metal-insulator-metal waveguide with one input port and n output ports. nxn equations are listed based on surface plasmon polariton (SPP) interference. Branch and bound method is introduced to find the optimal solutions to nxn equations. Two-color and three-color plasmonic demultiplexers are taken for examples, respectively. Finite element method (FEM) is carried on to verify our designs.
