Description
Summary:One of the most promising candidates for meeting nano-footprint expectations and producing intense coherent light in the deep subwavelength region is a plasmonic nano-laser that uses light matter interactions. However, because metal is an important constituent, these lasers face significant challenges in terms of dissipation losses. This paper presents a smaller footprints plasmonic-based nano-laser (nanowire-SiO 2 -Ag) explored for group III–V elements with the goal of selecting a material that is best suited as a gain material and harnessing maximum optical gain. This plasmonic nano-laser is tested for pump power with varying angle of incidence for GaP, GaSb, and InAs. It claims that when the angle of incidence is 20 and the maximum transmission coefficient is 0.5, this plasmonic nano-laser outperforms with the GaP nanowire. This can be attributed to fact that this serves as most suitable gain material compensating maximum for losses and provides best coupling and energy transfer to surface plasmon polariton along wire.
