Advanced Filters Help Space Lasers Deliver Internet from Above
Mar 5, 2024 — Rapid, on-demand access to information is a necessary facet of daily life in the present “age of communications.” The reliable communication links that society necessitates support person-to-person and device-to-device communications at any time and, increasingly, in any place. Such assurances of connectivity owe to the massive technological strides of the past half century. Now, as with many technology hallmarks of the previous 50 years — spanning hardline telephony to the current...
Measurement-based Quantum Compute Leaves Bottlenecks at the Gate
WAKO, Japan, Dec. 27, 2023 — Much of the progress so far in quantum computing has been done on so-called gate-based quantum computers. These devices use physical components, most notably superconducting circuits, to host and control the qubits. The approach bears similarity to...

UAVenture Capital Fund Invests in High-Power Laser Technologies
TUCSON, Ariz. Oct. 28, 2019 — UAVenture Capital Fund II LLC (UAVC), the University of Arizona's (UA's) in-house venture capital fund, announced it has invested in three new laser companies out of the university: DeUVe Photonics Inc., CThru Lasers Inc., and Wavelength Unlimited...
Lasers: A Unique Microscopy Source
Nov 2, 2018 — The optical microscope dates back to the time of Galileo. For most of the past century, microscopy was widely regarded as a ubiquitous and extremely mature field. Today, the picture is very different. Optical microscopy is an incredibly dynamic...
Label-Free Imaging Maps Brain Changes in Alzheimer's Mouse Model
WUHAN, China, Oct. 20, 2017 — An imaging system called cryo-micro-optical sectioning tomography (cryo-MOST) could help speed new drug development for Alzheimer’s disease by offering a better way to monitor the brain changes indicative of Alzheimer's in mouse models....
Solid-State Photodetector May Speed Switching of Optoelectronic Devices
NAGAKUTE, Japan, Sept. 9, 2016 — An all-solid-state-wavelength-dependent bipolar photodetector (WBPD), composed of a single semiconductor, has demonstrated a faster response time than existing WBPDs that are comprised of hetero-nanostructures. The novel WBPD has also demonstrated...
Nonlinear Light Manipulation Could Provide Basis for Optical Nanodevices
ST. PETERSBURG, Russia, Aug. 29, 2016 — Ultrafast nanoantenna switching between different light scattering modes, caused by the interaction between an intense laser pulse and the silicon of a nanostructure, could lead to devices that would enable ultrafast all-optical signal processing....
