Metal-Cavity Nanolasers

Abstract

Recent progress on nanoscale lasers, especially metal-cavity nanolasers, is highlighted. In spite of the metal loss, metal cavities of subwavelength scales have been used successfully for semiconductor lasers by optical or electrical pumping from low to room temperature. We focus on the demonstration of a substrate-free metal-cavity surface-emitting microlaser operating continuous wave at room temperature with electrical injection.
