Investigation Of Sub-Diffraction Mode Characteristics In A Semiconductor Plasmonic Nanolaser At Telecom Wavelength

Abstract Nanolasers are the key component in photonic integration and in this work we investigate the mode characteristics of an optically pumped Metal-Insulator-Semiconductor (MIS) plasmonic nanolaser structure at the sub-diffraction limit. The nanolaser structure consists of Ag/oxide/InGaAsP materials and operates at the telecom wavelength of…
