Abstract
Various embodiments may relate to an optical device. The optical device may include a stacked structure having a first surface and a second surface opposite the first surface. The stacked structure may include a plurality of holes or grooves extending from the first surface towards the second surface. The stacked structure may include a transition metal dichalcogenide material (TMDC) material. A thickness of the stacked structure may be of any value less than 100 nm.
Claims19
An optical device comprising:
- a stacked structure having a first surface and a second surface opposite the first surface;
- wherein the stacked structure comprises a plurality of holes or grooves extending from the first surface towards the second surface;
- wherein the stacked structure comprises a transition metal dichalcogenide (TMDC) material;
- and
- wherein a thickness of the stacked structure is of any value less than 100 nm;
- wherein the optical device is a super oscillatory lens (SOL), a super-critical lens (SCL), or a Fresnel zone plate configured to generate a sub-diffraction limit focusing spot, or a photon sieve configured to generate a hologram, upon light incident onto the optical device;
- and
- wherein the light is any one selected from a group consisting of visible light, ultraviolet (UV) light and infrared (IR) light.
