Binary PSO algorithm assisted to investigate the optical AND gate based- plasmonic nano- rods



  1. Opto-Electronic Department of Shiraz University of Technology, Shiraz, Iran


In this paper, a coherent perfect absorption (CPA)-type AND gate based on plasmonic nano particle is proposed. It consists of two plasmonic nano rod arrays on top of two serial arms with quartz substrate. The operation principle is based on the absorbable formation of a conductive path in the dielectric layer of a plasmonic nano-particles waveguide. Since the CPA efficiency depends strongly on the number of plasmonic nano-rod and the nano rod location, an efficient binary optimization method based the Particle Swarm Optimization (PSO) algorithm is used to design an optimized array of the plasmonic nano-rod in order to achieve the maximum absorption coefficient in the ‘off’ state and the minimum absorption coefficient in the ‘on’ state. In Binary PSO (BPSO), a group of birds consists a matrix with binary entries, control the presence (‘1’) or the absence (‘0’) of nano rod in the array..
