We demonstrated for the first time an azimuthally polarized laser source from an electrically driven metallic cavity nanolaser with a physical cavity volume of 0.146 λ3 (λ = 1416 nm). Single TE 01 mode lasing at 78 K was achieved by taking the advantages of the large free spectral range in such nanoscale lasers and the azimuthal polarization of lasing emission was verified experimentally. Mode shift controlled by device cavity radius was observed over a large wavelength range from 1.37 μm to 1.53 μm. Such metallic cavity nanolaser provides a compact electrically driven laser source for azimuthally polarized beam.
