Abstract

The present paper provides, for the first time, a design strategy for the achievement of room-temperature operation of electrically-injected metal-clad nano-spin VCSELs. The practical realization of such devices would represent the first application of the combined capabilities of three key technologies : plasmonics, spintronics and nano-technology. Rather subtle waveguiding effects arise in plasmonic lasers including the opportunity to significantly enhance the optical confinement factor. Exploitation of spintronic effects can enable reductions of up to 50 % in the lasing threshold current. The utilization of nanocavities gives access to Purcell- enhanced spontaneous emission for laser threshold reduction and, potentially, threshold-less lasing.
