We report room-temperature lasing from an optically pumped subwavelength-scale cylindrical InGaAsP pillar surrounded by circular Bragg reflectors on a metal substrate with a dielectric spacer layer. By taking advantage of wide in-plane photonic bandg

Highly aligned intrinsic and indium doped CdS nanopillar arrays were fabricated via a template assisted Solid Source Chemical Vapor Deposition method (SSCVD). The prepared nanopillar arrays were well aligned, dense and uniform in diameter and length.

We demonstrate that randomly distributed metallic nanowires on the dielectric-metal slab waveguides can form Fabry-Perot-type optical cavities and achieve sufficient quality factors for lasing for the transverse electric waveguide mode.

We propose a modified nanopatch cavity with a cuboidal semiconductor sandwiched between extended metal planes. Experimental results show the quality factor of ~200 can be achieved with an effective mode volume of ~0.0064 cubic wavelength.
