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 smart contact lens includes a contact lens, a nanostructures layer, a first sensor, a connector, and a smart module. The nanostructures layer may be anti-bacterial. The smart contact lens may be worn on an eye or may be implanted within an eye. The nanostructures layer is fabricated by depositing a colloidal dispersion onto an electrostatically-coated substrate. The colloidal dispersion is then removed and nanoholes are etched. The electrostatic coating is removed and a biocompatible material is spin-coated onto the substrate. Upon removal, a quasi-randomly distributed nanostructures layer forms.
