Abstract
An optical device as described herein includes a host substrate fabricated from a dielectric material transparent in the Infrared range. Additionally, the optical device as discussed herein includes multiple elements disposed on the host substrate. The multiple elements are spaced apart from each other on the host substrate in accordance with a desired pattern. Each of the multiple elements disposed in the host substrate is fabricated from a second material having a refractive index of greater than 4.5. Such an optical device provides an improvement over conventional optical devices that operate in the Infrared range.
