Abstract

 

A design for a metallo-dielectric nanolaser with electrical injection and coupled to an InP-membrane waveguide is presented. The structure supports a dielectric lasing mode near 1.55 µm with a high Q-factor due to a reflective metallic cladding. Threshold gain levels below 1000 cm-1 are predicted, which are compatible with room temperature operation under a current injection of a few tens of microamperes. Due to an efficient coupling to the waveguide, it represents a promising laser structure for ultra-compact photonic integrated circuits.
