Half-wave nanolasers and intracellular plasmonic lasing particles.

ABSTRACT: The ultimate limit for laser miniaturization would be achieving lasing action in the lowest-order cavity mode within a device volume of ≤(λ/2n)³, where λ is the free-space wavelength and n is the refractive index. Here we highlight the equivalence of localized surface plasmons and surface plasmon polaritons within resonant systems, introducing nanolasers that oscillate in the lowest-order localized surface plasmon or, equivalently, half-cycle surface plasmon polariton. These diffraction-limited single-mode emitters, ranging in size from 170 to 280 nm, harness strong coupling between gold and In_xGa_1-xAs_1-yP_y in the near-infrared (λ = 1,000-1,460 nm), away from the surface plasmon frequency. This configuration supports only the lowest-or
