Automotive Lighting Turns a Corner
Nov 1, 2023 — Studies cited by the Independent Institute for Highway Safety (IIHS) show that using automatic switching on old-fashioned high beams whenever possible reduces nighttime automotive crashes with animals, pedestrians, and unlit bicycles or cars by 26%. With the advent of inexpensive and rugged visible-range LEDs and other photonic technologies, automobile lighting is rapidly improving both inside and outside the vehicle.
On-Board Optics Expand Bandwidth and Reduce Power Use in the Data Center
Feb 3, 2023 — Co-packaged optics (CPO) and on-board optics (OBO) are not novel concepts, per se. The benefits of moving optics closer to the computing cores of data center switches have been clear to systems developers since optical glass fiber was first adopted...

VCSELs Increase Power and Wavelength for 3D Sensing
Jun 2, 2022 — For vertical-cavity surface-emitting lasers (VCSELs), the future looks bright — because their performance is rising while their price is falling. On the horizon is also a move from near-IR to shortwave IR wavelengths. These trends will help...
TRUMPF Leads Funding Round for Optical MEMS Microphone Company
DITZINGEN, Germany, May 2, 2022 — SensiBel, an Oslo, Norway-based microphone technology company, closed a €15 million (~$15.8 million) funding round to ramp up production of its optical MEMS microphone technology. TRUMPF Venture GmbH led the funding round, which sensiBel said...
Advancements in Diode Lasers Fuel Automotive Lidar
Jan 27, 2022 — Lidar for autonomous vehicles debuted in 2007 as an enabling sensor technology for robotaxis and robotruck development. Within the last five years, however, the technology has trended toward broader commercialization in mass-market passenger...
VCSEL Addition Helps AI Light-Field Camera Read Facial Expressions
DAEJEON, South Korea, Jan. 24, 2022 — A team at the Korea Advanced Institute of Science and Technology (KAIST) has developed a technique for facial expression detection by merging near-infrared (NIR) light-field camera imaging techniques with AI technology. Unlike a conventional camera,...
Photonics News: Week in Brief: 01/07/22
Jan 7, 2022 — VELDHOVEN, Netherlands — ASML Holding experienced a fire inside part of its factory in Berlin during the night of Jan. 2. The fire, in the company’s Berliner Glas facility, was extinguished; there were no injuries during the incident....
Demand for MIR Photonics Rises on New Gas Analysis Applications
Nov 29, 2021 — Real-time precision gas analysis is critical to a wide range of industries, including medical diagnostics, emissions monitoring, and semiconductor fabrication. The relatively simple molecular structure of most gases makes them ideal candidates for...
Photonic Chip Combines Many VCSELs into Single Laser
WÜRZBURG, Germany, Sept. 30, 2021 — Researchers from the Technion-Israel Institute of Technology and the University of Würzburg successfully forced an array of vertical-cavity lasers to act together as a single laser — a highly effective laser network the size of a grain of...
