Abstract
This disclosure provides systems, methods, and apparatus related to nanometer scale lasers. In one aspect, a device includes a substrate, a line of metal disposed on the substrate, an insulating material disposed on the line of metal, and a line of semiconductor material disposed on the substrate and the insulating material. The line of semiconductor material overlaying the line of metal, disposed on the insulating material, forms a plasmonic cavity.
Claims12
A device comprising:
- a substrate;
- a line of metal disposed on the substrate;
- an insulating material disposed on the line of metal;
- and
- a line of semiconductor material disposed on the substrate and the insulating material, wherein the line of semiconductor material overlaying the line of metal, disposed on the insulating material, forms a plasmonic cavity.

A device comprising:
- a substrate;
- a first and a second line of metal disposed on the substrate, the first and the second line of metal being substantially parallel;
- an insulating material disposed each of the first and the second line of metal;
- and
- a first, a second, and a third electrode disposed on the substrate, the lines of metal and the electrodes arranged such that the first line of metal is between the first and the second electrodes and the second line of metal is between the second and the third electrodes;
- and
- a line of semiconductor material overlaying the first line of metal, disposed on the insulating material, forming a first plasmonic cavity, and overlaying the second line of metal, disposed on the insulating material, forming a second plasmonic cavity.
