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: Optical spectrometers and polarization state hybrid sensors may be used to determine the spectral and polarization state components of electromagnetic waves. Hybrid sensors may be bulky devices and require waves to enter at a nearly direct angle of incidence to record a measurement. What is disclosed is an ultra-compact polarization state sensor with nanophotonic components. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering, anisotropic 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 sensor may be capable of handling about 200 nm bandwidth. The sensor may be able to read image data in the visible and to read spectral and polarization state data in the infrared wavelength range. The surface area of the sensor may be about 1 mm2, allowing it to fit on mobile devices.
