Design and Fabrication of Room Temperature Electrically Pumped ZnO Nanowire Hybrid Plasmonic Lasers

Abstract

Plasmonic lasers have attracted much attention because they can break through the diffraction limit, but due to the large metal loss limitations, electrically driven plasmonic lasers mainly work at low temperatures to achieve sufficient gain. Therefore, we proposed electrically pumped nanowire plasmonic lasers at room temperature. Here, the metal/insulator/semiconductor (MIS) structure was applied to reduce the metal loss by separating the active area and the metal layer through the insulator. We illustrate the superiority of plasmonic laser performance by comparing plasmonic and photon lasers at room temperature. Our research provides some experimental basis for the realization of future optoelectronic integration.
