Plasmonic nanowire laser using one dimensional photonic crystal structure

Abstract

Plasmonic lasers amplify the light coupled to oscillating electrons so that by adding momentum it becomes viable to have dimensions beyond diffraction limit of course this ability to focus light has the drawback of high losses at the metal surface. In this research considering the properties of periodic structures we formed the idea that placing plasmonic lasers in periodic structures may lead to distinct properties which are not seen in single plasmonic lasers. Simulation results for ZnO nanowire plasmonic laser show that in one dimensional periodic structures the dependency of the radiation light to the angle of incidence is increased so that one additional degree of freedom is obtained for controlling the nanolaser operation besides the minimum diameter of the nanowire to observe lasing is decreased from 120nm to 80 nm.
