Abstract: An integrated optical assembly includes an optics mount. The optics mount has disposed thereon a light source for providing a beam of light and a lens configured to focus the beam of light. The integrated optical assembly includes a photonic integrated circuit (PIC) mechanically coupled to the optics mount. The PIC has disposed thereon a grating coupler for receiving the beam of light and coupling the beam of light into a waveguide. The integrated optical assembly includes a microelectromechanical systems (MEMS) mirror configured to receive the beam of light from the lens and redirect it towards the grating coupler. A position of a reflective portion of the MEMS mirror is adjustable to affect an angle of incidence of the beam of light on the grating coupler.

Abstract: An apparatus and a camera system are provided. The apparatus includes an imaging screen configured to diffuse incoming light, and a lens system coupled to the imaging screen and configured to focus light from the imaging screen onto a CMOS image sensor. The imaging screen includes a ceramic diffuser layer fused into a surface of a glass substrate, and a thickness of the ceramic diffuser layer is within a range of about 7-10 μm.

Abstract: An optical circuit switch includes a fiber hole array, a plurality of internal optical fibers, a collimating lens array, a MEMS mirror array, and a reflective surface. The fiber hole array includes an array of receptacles shaped to accept respective internal optical fibers. The collimating lens array is positioned adjacent to the fiber hole array. Each collimator of the collimating lens array optically couples light into or out of a corresponding one of the internal optical fibers. The fiber hole array, the collimator, the MEMS mirror array and the reflective surface are positioned relative to one another such that light exiting each of the internal optical fibers passes through its corresponding collimator and is redirected by a first mirror within the MEMS array towards the reflective surface, which directs the light back towards a second mirror of the MEMS mirror array, which in turn redirects the light towards a second internal optical fiber.
