Abstract: Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.

Abstract: A pixel for an image sensor includes a microbolometer sensor portion, a visible image sensor portion and an output path. The microbolometer sensor portion outputs a signal corresponding to an infrared (IR) image sensed by the microbolometer sensor portion. The visible image sensor portion outputs a signal corresponding to a visible image sensed by the visible image sensor portion. The output path is shared by the microbolometer and the visible image sensor portions, and is controlled to selectively output the signal corresponding to the IR image or the signal corresponding to the visible image. The output path may be further shared with a visible image sensor portion of an additional pixel, in which case the output path may be controlled to selectively to also output the signal corresponding to a visible image of the additional pixel.

Abstract: A filter for an imaging device includes an array of phase-modulating nanostructures formed on a substrate. At least one phase-modulating nanostructure of the array of phase-modulating nanostructures changes a phase of incident light a predetermined amount based on a first width and a second width of the phase-modulating nanostructure in which the first width is perpendicular to the second width. In one embodiment, the filter focuses light incident on the filter towards a center a pixel of an image sensor at an image plane. In another embodiment, the phase-modulating nanostructure is formed from a material having a refractive index that is greater than 1.9. The filter can also be used to form a quarter-wave plate.

Abstract: A pixel for an imaging sensor is disclosed that includes a photodetector and a metasurface. The photodetector includes a first surface and sidewalls that extend into the photodetector in a first direction from the first surface. The metasurface is formed on the first surface and includes nanostructures that bend a predetermined range of wavelengths of light at least 70 degrees in opposing angles from a direction that is substantially perpendicular to the first surface, and a standing wave pattern forms in an active region of the pixel. The predetermined range of wavelengths of light includes 700 nm to 1100 nm inclusive. In one embodiment, the pixel is a silicon-based photodetector, a thickness of the pixel in the first direction is less than or equal to 5 μm, and the pixel absorbs at least 20% of a power of the predetermined range of wavelengths of light.

Abstract: A metalens includes one or more regions of nanostructures. A first region of nanostructures directs a first field of view (FOV) of light incident on the first region of nanostructures to a first region of an image plane. A second region of nanostructures directs a second FOV of light incident on the second region of nanostructures to a second region of the image plane in which the second FOV is different from the first FOV, and the second region of the image plane is different from the first region of the image plane. A third region of nanostructures directs a third FOV of light to a third region of the image plane, in which the third FOV is different from the first FOV and the second FOV, and the third region of the image plane is different from the first region and the second region of the image plane.
