N2 - Triangular metal groove/wedge based hybrid plasmonic structures are leveraged for nanolaser applications. It is shown through numerical simulations that by controlling the tip angle of the triangular metallic substrate, tunable lasing properties can be readily achieved. On the one hand, metal substrates with grooves could benefit enhanced optical confinement and meanwhile results in a reduced lasing threshold with carefully engineered tip angles. While on the other hand, metal wedge based structures could be used to further scale down the size of the stimulated optical mode, potentially enabling the realization of ultra-deep-subwavelength laser action. These novel structures could perform as efficient subwavelength light sources with flexible lasing properties, thereby facilitating diverse applications in future advanced active photonic systems.
