Abstract
Multilevel leaky-mode optical elements, including reflectors, polarizers, and beamsplitters. Some of the elements have a plurality of spatially modulated periodic layers coupled to a substrate. For infrared applications, the optical elements may have a bandwidth larger than 600 nanometers.
Claims10
An optical element comprising:
- a substrate;
- and
- a plurality of spatially modulated periodic layers coupled to the substrate, wherein the plurality of spatially modulated periodic layers are configured to produce leaky mode resonance in response to an incident electromagnetic wave;
- where the leaky mode resonance induces a substantially constant reflectance or transmittance over a bandwidth greater than 600 nanometers.
