Publication number: 20240118554Abstract: Multi-wavelength light is directed to an optic including a substrate and metasurface optical components deposited on a surface of the substrate. The metasurface optical components comprise a pattern of silicon dielectric resonators with nonperiodic gap distances between adjacent dielectric resonators. Incident light directed to the metasurface optical components is scattered and phase-shifted by the configuration of the gap distances and the widths and thicknesses of the dielectric resonators. Each dielectric resonator has a rectangular cross-section such that a first phase shift is imparted for a transverse-electric (TE) component of the incident light and a second phase shift is imparted for a transverse-magnetic (TM) component of the incident light.Type: ApplicationFiled: July 11, 2023Publication date: April 11, 2024Applicant: President and Fellows of Harvard CollegeInventors: Francesco Aieta, Mikhail Kats, Patrice Genevet, Federico Capasso, Mohammadreza Khorasaninejad

Patent number: 10791304Abstract: The functional effect of having additional color-sensing cone types in the human eye is implemented by an encoding of some spectral information differently for the left and right eyes. This different encoding for identical features seen by the left and right eyes is interpreted as a perceptively different feature by the human brain, allowing additional spectral information to be conveyed through the limited tristimulus sensitivity of the human eye.Type: GrantFiled: August 3, 2017Date of Patent: September 29, 2020Assignee: Wisconsin Alumni Research FoundationInventors: Mikhail A.

Patent number: 9952096Abstract: A spectral encoder includes a thin layer of lossy dielectric material whose thickness varies transversely from 0 to a thickness of about ?/4n (e.g., <100 nm), where ? is the wavelength of incident radiation and n is the dielectric material's refractive index. The dielectric layer reflects (and/or transmits) light at a wavelength that depends on the layer's thickness. Because the dielectric layer's thickness varies, different parts of the dielectric layer may reflect (transmit) light at different wavelengths. For instance, shining white light on a dielectric layer with a linearly varying thickness may produce a rainbow-like reflected (and/or transmitted) beam. Thus, the spectral encoder maps different wavelengths to different points in space. This mapping can be characterized by a transfer matrix which can be used to determine the spectrum of radiation incident on the spectral encoder from the spatial intensity distribution of the radiation reflected (and/or transmitted) by the spectral encoder.Type: GrantFiled: June 3, 2013Date of Patent: April 24, 2018Assignee: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Mikhail A.

Patent number: 9923112Abstract: A solar cell receiver for use in a concentrating solar system which concentrates the solar energy onto a solar cell for converting solar energy to electricity. The solar cell receiver may include a solar cell mounted on a support and with one or more III-V compound semiconductor layers.

An encapsulant may be positioned over the support and contained between the optical element and the frame. The encapsulant may have enlarged heights at contact points with the optical element and the frame and a reduced height between the contact points away from the optical element and the frame. The solar cell receiver may be used in a solar cell module.Type: GrantFiled: June 24, 2014Date of Patent: March 20, 2018Assignee: SUNCORE PHOTOVOLTAICS, INC.Inventors: Lei Yang, Sunil Vaid, Mikhail Kats, Gary Hering, Philip Blumenfeld, Damien Buie, John Nagyvary, James Foresi, Peter Allen Zawadzki
