This paper explores the role of nanotechnology with focus on nanophotonics in dielectric, metal, and semiconductor inhomogeneous metamaterials and devices for optical communications, information and signal processing, and sensing.
We report pulsed room temperature lasing from optically pumped subwavelength metal-insulator-semiconductor structures. The lasers consist of InGaAsP gain disks embedded in a SiO2/aluminum bi-layer. Lasing at 1520 nm from a 730 nm gain core is demonstrated.
