Policymakers and appointed officials outlined many of the U.S. government’s foremost priorities in science and technology, joining with leaders from the photonics sector in Washington, D.C., last week for the second SPIE Photonics Industry Summit. The one-day summit placed a premium on using industry collaboration to help spur economic and technological advancement, with additional focus on workforce development and education.

The event built on last year’s inaugural Industry Summit, which SPIE held six weeks after the CHIPS and Science Act was signed into law. The legislation factored prominently in the program again in 2023, with the road to securing funding under the Chips and Science Act placing high up among...]]> https://www.photonics.com/Articles/Critical_Tech_Policy_Priorities_at_the_Fore_of/a69366 A69366 Mon, 02 Oct 2023 07:00:00 GMT
Monroe Community College received a $5.1 million grant from the Department of Defense’s Manufacturing Engineering Education Program (MEEP) to fund its optics and photonics associate degree programs. The funding is part of $53 million recently distributed by the National Defense Education Program to 13 organizations. This is the second time Monroe has been awarded funding through the MEEP program, as the nation’s first community college to administer associate degrees in precision optics.

In 2000, Berthold Leibinger, the man who brought laser technology into Germany’s TRUMPF Group, established the Innovation Award — expressed in native German as the “Innovationspreis” — to honor outstanding R&D in the field of laser technology. Next to this prestigious award, the Berthold Leibinger Zukunftspreis was added in 2006 to recognize scientists driving fundamental laser research to new heights.

Leibinger sadly passed away a few weeks after the Innovationspreis ceremony in 2018, but he had handed the company over to his children years before, along with the Berthold Leibinger Foundation and its associated awards.

At the 2023 ceremony, held on September 22 in Ditzingen, the Foundation...]]> https://www.photonics.com/Articles/Berthold_Leibinger_Awards_Honor_Laser_Research_at/a69354 A69354 Tue, 26 Sep 2023 09:45:00 GMT

The ability to measure the size and color of the light at the same time could improve a crucial step in chipmaking — lithography — by enabling lithography machines to make smaller, faster chips. To produce the microsize chips used in most electronic devices, lithography machines need precision-engineered lenses, mirrors, and light sources.

A thin-film, amplitude-only spatial light modulator made from phase-change-based material was developed by researchers at the University of Exeter and the Institute of Optics in Madrid.

The device operates in reflection and modulates the amplitude of light incident on its surface with virtually no changes to the optical phase. When the phase-change material is switched between its amorphous and crystalline states, there is no effect on optical phase.

Because phase-change materials can be switched on sub-microsecond timescales, the chalcogenide-based device could provide a route to the development of ultrafast spatial light modulators, with applications in fields such as wavefront shaping, communications, sensing, and imaging....]]> https://www.photonics.com/Articles/Amplitude-Only_Light_Modulator_Could_Improve/a69257 A69257 Mon, 21 Aug 2023 07:00:00 GMT
Diffuse in vivo flow cytometry (DiFC), an optical technique developed at Northeastern University, enables fluorescence detection of tumor cells circulating in the bloodstream. It is a promising technique for detecting cancer that has metastasized. However, due to signal-to-noise ratio (SNR) constraints, which are attributed mainly to background autofluorescence in the tissues, DiFC’s measurement depth is limited.

A team from Tufts University and Northeastern University is working to address this issue and take the DiFC method developed by the Northeastern group to a new level. The researchers are investigating whether a new method developed by the Tufts group, called the dual-ratio (DR) approach, can minimize noise and...]]> https://www.photonics.com/Articles/Optical_Measurement_Methods_Combine_to_Detect/a69231 A69231 Thu, 10 Aug 2023 07:00:00 GMT
Through its existing European subsidiary Photonics Management Europe srl, Hamamatsu Photonics submitted an application to the Danish Business Authority to acquire shares in NKT Photonics. The acquisition would result in NKT being made subsidiary to Photonics Management Europe and sub-subsidiary to Hamamatsu. The application is a follow-up to Hamamatsu’s June 2022 bid to acquire NKT Photonics — a move that the Danish Business Authority blocked in May this year. Hamamatsu said it will conduct activities to obtain approval promptly, including consultations with relevant Danish authorities.

Electron spins could become more efficient and easier to manage through a light-based approach using halide perovskite semiconductors. Research teams at Harvard’s Rowland Institute and the University of Cambridge observed ultrafast spin-domain formation in polycrystalline halide perovskite thin films in response to irradiating the films with circularly polarized light at room temperature.

Photoinduced spin-charge interconversion in semiconductors, with spin-orbit coupling, could provide a route to spintronics that does not require external magnetic fields, which are challenging to control. An electron can have two spin states, up or down, and these states can be used to store and process information. But manipulating spin...]]> https://www.photonics.com/Articles/Optically_Addressed_Spintronics_Eliminates_Need/a69140 A69140 Wed, 05 Jul 2023 07:00:00 GMT
A team of researchers at the University of Ottawa developed a terahertz (THz) spectroscopy technique for recording movies in real time at 50,000 fps.

High-speed video captures and slow-motion movies allow scientists to observe the mechanical dynamics of complex phenomena in detail. When the images in each frame are replaced by THz waves, the movies make it possible to monitor low-energy resonances and fast structural and chemical transitions in sample materials. As a result, the THz spectroscopy system, developed in collaboration with researchers from the Max Planck Institute for the Science of Light, could become a powerful tool for observing phenomena that are currently impossible to investigate because they are too fast,...]]> https://www.photonics.com/Articles/Time-Resolved_Spectroscopy_Peers_in_on/a69118 A69118 Mon, 26 Jun 2023 07:00:00 GMT

To help broaden the use of single-photon avalanche diode (SPAD) cameras for multispeckle diffuse correlation spectroscopy (DCS), researchers at the University of Edinburgh developed a data compression scheme for a large-pixel-count SPAD camera using a field-programmable gate array (FPGA).

The camera system’s large sensor array enabled a substantial signal-to-noise ratio (SNR) gain over a single-pixel system: The researchers demonstrated an SNR gain of 110, with respect to single-pixel multispeckle DCS, using half of the 192 × 128 SPAD array. The pixel active fill factor was 13% — an order-of-magnitude-larger pixel count than in prior works, according to the team.
