Abstract

Claims (16)

1 . A metasurface module comprising:

a secondary substrate; and

a metasurface chip mounted on the secondary substrate,

wherein the secondary substrate laterally extends from all sides of the metasurface chip to completely surround the metasurface chip; and

wherein the secondary substrate is coated with a coating; wherein the coating includes patterned features and the metasurface chip is aligned with the patterned features.

2 . The metasurface module of claim 1 , wherein the coating is at least one selected from the group consisting of: an opaque optical aperture, an anti-reflection coating, an optical filter coating, an electrical circuit, and a conductive layer.

3 . The metasurface module of claim 2 , wherein the optical filter coating comprises at least one selected from the group consisting of: a high-pass coating, a low-pass coating, and a band-pass coating.

4 . The metasurface module of claim 2 , wherein the conductive layer is configured to provide eye safety.

5 . The metasurface module of claim 1 , wherein the metasurface chip is mounted to the secondary substrate by an optically transparent bond.

6 . The metasurface module of claim 1 , further comprising a housing, wherein the secondary substrate is mounted to the housing.

7 . A metasurface module comprising a metasurface chip completely surrounded by a polymer material; wherein the metasurface chip is coated with a coating; wherein the coating includes patterned features and the metasurface chip is aligned with the patterned features.

8 . The metasurface module of claim 7 , wherein the polymer material is coplanar with a top surface of the metasurface chip.

9 . The metasurface module of claim 7 , wherein the coating is at least one selected from the group consisting of: an opaque optical aperture, an anti-reflection coating, an optical filter coating, an electrical circuit, and a conductive layer.

10 . The metasurface module of claim 9 , wherein the optical filter coating comprises at least one selected from the group consisting of: a high-pass coating, a low-pass coating, and a band-pass coating.

11 . The metasurface module of claim 9 , wherein the conductive layer is configured to provide eye safety.

12 . The metasurface module of claim 7 , further comprising a housing, wherein the metasurface chip is mounted to the housing through the polymer material.
