Patent ID: 11860336
Assignee: PRESIDENT AND FELLOWS OF HARVARD COLLEGE
Field: Optics (Instruments)
Classification: CPC G  B | IPC B  G

Claim 0:
1. An optical device, comprising:
a non-metallic membrane comprising a plurality of apertures extending at least partially through a thickness of the non-metallic membrane, configured to:
structure incoming light having a wavelength to produce modified light, wherein the wavelength of the incoming light in vacuum is in a range from ultraviolet light to mid-infrared light; and
transmit the modified light through the non-metallic membrane or reflect the modified light away from the non-metallic membrane;

wherein a separation between each of the plurality of apertures is subwavelength relative to the wavelength of the incoming light;
wherein a width of each of the plurality of apertures is subwavelength relative to the wavelength of the incoming light; and
wherein a length of each of the plurality of apertures is wavelength-scale relative to the wavelength of the incoming light.
