Various embodiments disclosed relate to an assembly. The assembly includes a compound parabolic concentrator including an exit aperture that has a generally circular perimeter, which defines a circumference of the exit aperture. The assembly further includes a photodiode sensor generally that is aligned with the exit aperture of the compound parabolic concentrator. An optical adhesive layer adheres the exit aperture of the compound parabolic concentrator to the photodiode sensor. A protrusion extends between at least a portion of the perimeter of the compound parabolic concentrator exit aperture and the photodiode.

Disclosed herein are display and photonic devices utilizing metasurfaces. An optical device comprising an optical component and an optical transmission medium is disclosed. A waveguide couples the optical component and the optical transmission medium. A metasurface is disposed on an end of the waveguide and arranged to increase an optical coupling between the waveguide and the optical transmission medium. Additionally, a display comprising a number of light emitting elements and a metasurface for each of the light emitting elements. The metasurface arranged to eliminate screen door effect in virtual reality display systems.

Metasurface devices for display and photonics devices

An apparatus comprising a first reference element having an output power that varies monotonically with input frequency over an operating frequency range and receiving at least a portion of an output beam of light from an optical source. A second reference element having an output power that is frequency dependent receives at least a portion of the output beam of light. A first optical detector measures the power of a first reference beam of light from the first reference element. A second optical detector measures the power of a second reference beam of light from the second reference element. Electronic circuitry is coupled to the first and second optical detectors for receiving first and second reference signals therefrom and producing a coarse error signal for permitting coarse adjustment and a fine error signal for permitting fine adjustment of the frequency of the output beam of light.
