Abstract:
1. A plasmonic light collector for guiding light into a transmission cable through an opening in the plasmonic light collector, comprising: a first dielectric layer, wherein the first dielectric layer has a positive dielectric constant; a first negative effective dielectric constant layer formed on the first dielectric layer, wherein the first negative effective dielectric constant layer has a negative effective dielectric constant, wherein the opening comprises an opening in the first dielectric layer and the first negative effective dielectric layer, and wherein the opening is configured to guide the light into the transmission cable using an interaction between the light and plasmons associated with the opening; a second dielectric layer formed on the first negative effective dielectric constant layer, wherein the second dielectric layer has a positive dielectric constant; and a second negative effective dielectric constant layer formed on the second dielectric layer, wherein the second negative effective dielectric constant layer has a negative effective dielectric constant, and wherein the opening further comprises an opening in the second dielectric layer and the second negative effective dielectric layer.
