Mass-Production Method Aims to Drive Metalenses Toward Widespread Commercial Use
POHANG, South Korea, April 8, 2024 — With their ability to manipulate light and potential to drastically reduce the size and thickness of optical components, metalenses show great promise, especially for applications in the NIR region. However, tens of millions of won — thousands...
Metalenses Scale Up to Target the Market for Small Optics
Mar 3, 2023 — Earlier this year, the first wave of smartphones equipped with STMicroelectronics’ second-generation direct time-of-flight (TOF) sensor reached the consumer market. The sensor includes planar metasurface optics. The metalens-enabled sensor...
Lithography Technique Precisely Controls Nanodevice Feature Sizes
HONG KONG, April 19, 2022 — Researchers at the University of Hong Kong (HKU) developed an approach for nanodevice fabrication to increase the efficiency of building nanostructures that require spatially different dimensions. The researchers devised and demonstrated a...
Camera the Size of a Gran of Salt Performs Beyond its Scale
PRINCETON, N.J., Dec. 17, 2021 — Researchers at Princeton University and the University of Washington (UW) designed a nanosize camera, no bigger than a grain of salt, that produces images comparable to those produced by a traditional lens setup more than 500,000 times larger than...
Startup Expects to Bring Metalens Technology to Commercial Market in 2022
CAMBRIDGE, Mass., Feb. 9, 2021 — Metalenz, the Harvard University-originating startup that last week received exclusive license to flat-optics innovations developed in the lab of Federico Capasso, said that the long-awaited metalens technology will likely see introduction into the...
Moiré Metasurfaces Extend Focal Length Tunability
TOKYO, Jan. 6, 2021 — Researchers form Tokyo University of Agriculture and Technology (TUAT) have demonstrated that moiré metalenses can tune focal length along a wider range than previously seen. Moiré metalenses are tiny patterned lenses composed of...
Researchers Demonstrate VCSEL Control Using Ultrathin Metalenses
NICE, France, Feb. 12, 2020 — Researchers led by Patrice Genevet of the Centre de Recherche sur l’Hétéro-Epitaxie et ses Applications (CRHEA) at the University Côte d’Azur and collaborators at the Key Laboratory of Optoelectronics Technology at...
The Dawn of New Optics: Emerging Metamaterials
Nov 19, 2018 — Science has long sought novel or modified materials that could reach beyond the conventional laws of optics to replace bulky glass and polymer optical components with flatter, more robust, lower-cost, stackable ones — perhaps even with subwavelength...
Capasso Group Develops Flat Lenses with Same Technology Used to Make Chips
CAMBRIDGE, Mass., July 5, 2018 — Optics and lenses are everywhere. They’re in laptops, cameras, and telescopes. Focusing the entire visible spectrum with lenses has been a challenge because each wavelength moves through materials at different speeds. Red wavelengths will move...
Single Metalens Focuses all Colors of the Spectrum in one Point
CAMBRIDGE, Mass., Jan. 25, 2017 — Metalenses are flat surfaces that use nanostructures to focus light. These simple, flat surface lenses could replace bulky, curved lenses currently used in optical devices. Researchers at the Harvard John A. Paulson School of Engineering and Applied...
