Abstract

We report continuous wave lasing operation at T=260 K of subwavelength-metallic-cavities with semiconductor core encapsulated in silver under electric injection. The physical cavity volumes of the two lasers presented are 0.96 λ3 (λ=1563.4 nm) and 0.78 λ3 (λ=1488.7 nm), respectively. Longitudinal modes observed in one of lasers correspond to the Fabry-Perot cavity in the length direction. Such record high temperature operation of a subwavelength laser is of great importance for the development of small light sources in future integrated photonic circuits and other on-chip applications.
