STEM Programs Struggle to Satisfy the ‘Endless Demand’ for Photonics Talent
Earlier this year, at a major recruitment event at the University of Arizona’s Wyant College of Optical Sciences, the job openings listed outnumbered students in attendance. This imbalance exemplifies the immense pressure STEM programs across the country face in meeting photonics industry workforce demands.

More than Skin Deep: Photonics Protects Our Cultural Heritage
For hundreds of years, analysis trumped preservation when it came to irreplaceable cultural heritage objects such as paintings, icons, and written works. Today, conservators avoid taking even tiny samples from works of priceless art, making photonics technology an invaluable addition to cultural heritage research.

The Second Quantum Revolution Needs Reinforcements
The infancy of the second quantum revolution is upon us. Although the technologies driving this revolutionary struggle are not yet mature, they are attracting a great deal of interest and investment from both government and private organizations. While market projections for the quantum industry are inconsistent, they continue to help spur the momentum. All indications point to double-digit near-term growth. This is good news for investors but not for hiring managers, who face a scarcity of workers to meet the sector’s demands.

Petawatt System Generates Gamma Rays for Industrial Applications
A project that aims to demonstrate the efficient generation of dense gamma-ray beams will include experiments that are expected to provide the first statistically relevant study of gamma-ray generation using high-powered lasers. The researchers on the project hope that the work will open the way for secondary high-energy photon sources that can be used for a range of industrial applications. These include materials science, nuclear waste imaging, nuclear fuel assay, security, and high-resolution deep-penetration radiography in addition to fundamental physics studies.

Ultrathin Light-Field Imaging Film Yields Vivid 3D Images

Soochow University researchers developed an ultrathin film based on light-field imaging — a technology that creates 3D images by capturing the direction and intensity of all light rays in a scene. The 25-µm-thick film, which is made with low-cost materials, provides a glass-free approach to 3D imaging and offers a full field of view. It produces 3D images that are viewable under normal light and without the need for special reading devices.

QCL Dual-Comb Spectroscopy Matures into the Mid-Infrared by Combining High-Time and High-Frequency Resolution
Tue, Aug 23, 2022 10:00 AM - 11:00 AM EDT
QCL dual-comb spectroscopy began with high time-resolved (250 µs-250ms) single shot measurements and has progressed to time-scales that can compete with rapid scan Fourier-transform infrared spectroscopy. Recent research has discovered a high-spectral resolution feature on instruments that allows measurements with less than one MHz resolution over a bandwidth of 50cm-1. This breakthrough was achieved by combining the high-time resolved mode with the high-spectrally resolved mode in supersonic beam measurements. Andreas Hugi, Ph.D. explains the technical background of these acquisition modes and links them to real world applications. Sponsored by Hamamatsu Corp.
