Nanowire lasers:

These are nanoscale lasers with the potential of optical interconnects and optical data communication on-chip.

Nanowire lasers are built from compound 111 - V semiconductor heterostructures, the high refractive index allows for low optical loss in the nanowire core.

Nanowire lasers are subwavelength lasers of only a few ho hundred nanometers. Nanowire lasers are fabyPerd resonator cavities defined by the end facets of the wire with high reflectivity recent developments have demonstrated reputation rales greater than $200 \mathrm{GHz}$ othering possibilities for optical chip-level communications.
