SPIE Joins 50+ Scientific Groups Expressing Concern on an Executive Order for Scientific Grants

ECOC Exhibition 2025 is wrapping up in Copenhagen. We have all the highlights, including emerging tech and award-winning companies. SPIE joins a massive list of scientific organizations writing to Congress to express concern over an executive order on scientific grants. The groups say this latest order could lead to politicizing areas of research. Researchers from the California NanoSystems Institute at UCLA have developed a new light-emitting material that could transform photonics. IonQ is reporting the successful demonstration of visible-to-telecom wavelength frequency conversion. Germany announces plans to invest more than $40 billion in space-related defense systems. Photonics21 is asking European leaders to invest €2 billion in photonics. Quantum Computing Inc. raises $500 million in the private sale of common stock. And SPIE Photonics West is now open for registration! Sponsored by Edmund Optics and Thorlabs.

Caltech Research Enables Coherent Spectral Broadening On-Chip

Broadband, coherent light sources are highly valued in R&D. But until now, they have been difficult to achieve without bulky, inefficient tabletop devices. A Caltech team led by professor Alireza Marandi developed an efficient solution to integrating a broad spectrum of frequencies on a microchip. Using an optical parametric oscillator, the team demonstrated multi-octave frequency comb generation on a nanophotonic device with a threshold of only femtojoules of pump energy. Read Article

Multi-Camera Microscope Produces Sharp Images of Large, Curved Samples

Microscopy samples are seldom completely flat across a centimeter-scale field of view. Mechanical scanning can keep all the parts of a large sample in focus, but scanning reduces throughput, slowing the imaging process. To help large-area microscopy systems resolve trade-offs between field of view, resolution, and imaging speed, a team at Duke University developed a single-shot, re-imaging microscope that achieves seamless, gigapixel imaging over a 16.3 x 18.8 square millimeter field of view, at 0.84-µm half-pitch resolution, without mechanical scanning.

Scalable 3D Micro-Printed Sensors Promise Optofluidic Disease Detection

Early-stage disease diagnosis relies on the highly sensitive detection of biomarkers, such as optical whispering-gallery-mode (WGM) microcavity sensors; such devices provide precise, label-free biosensing. However, scaling and integrating large-scale arrayed WGM microcavity sensors is challenging. Bottlenecks in sensor design can lead to these bottlenecks. In response, researchers at Hong Kong Polytechnic University developed a 3D micro-printed WGM micro-laser sensor for sensitive on-chip biosensing. Read Article

T165 Laser Diode Pulser

Highland Technology Inc.
The T165 is a picosecond to nanosecond laser diode pulser that incorporates an edge-triggered pulse generator with fast rise and fall times into a butterfly or TO-packaged laser. Its 2" x 2" design connects directly to standard 0.1" pin-pitch butterfly laser packages, making it ideal for OEM use in laser systems. Laser current, bias, and pulse widths are settable with onboard trimpots or via external analog inputs.

The Power of Inertial Confinement Fusion — With Omar Hurricane and Mike Campbell

There is an ever-growing demand for power, whether it is to supply electricity for our power-hungry AI servers or to keep the lights on in more homes. Inertial confinement fusion has been referred to as one of the most promising paths to thermonuclear fusion, and it could one day provide a path to more efficient power. Omar Hurricane and Mike Campbell formed a professional relationship and a lasting friendship through their time together at the Lawrence Livermore National Laboratory. In this episode of “All Things Photonics”, they discuss the progress made in inertial confinement fusion and what this technology will need to reach its full potential.
