This phase-matching method unlocks both efficient THz generation from femtosecond optical pulses and sensitive THz detection on the same chip. From chip to free space Many real-world applications require THz signals to radiate into free space. To bridge this gap, our team integrated planar antennas directly onto the lithium niobate chip. These antennas couple the […]

These reticles are not just patterns etched in glass but act as the interface between operator and target, the fine line that translates a decision into action. By producing them within cleanroom environments and applying advanced coatings, we ensure they withstand harsh use while preserving absolute clarity. This capability also opens doors to customized designs

Innovative LiDAR/TLS 3D scanning method LiDAR works by emitting laser pulses and measuring the time they take to return (time of flight) from scanned surfaces, which generates a dense 3D point cloud (a spatial dataset with x, y, and z coordinates).  “TLS technology offers high accuracy but is costly and challenging to operate inside caves,

When the pump laser was circularly polarized, time reversal symmetry (in which behavior remains the same whether time runs forward or backward) was broken and a topological gap was opened (with Chern number C=1). “On the other hand, when the pump laser is linearly polarized the gap remains closed,” Zhen says. “Essentially, we verified all

In this episode of Photonics Hot List: Diagnosing diabetes typically requires invasive, expensive lab work. But Penn State researchers are making the process simpler with a sensor that can diagnose via just a breath sample. Laser and machine tool manufacturer TRUMPF is joining forces with technology company Siemens to accelerate digital manufacturing and AI readiness.

In an advance for frequency combs, Alireza Marandi, a professor of electrical engineering and applied physics at Caltech, and his team recently created a nanophotonic device to produce a broad range of laser light frequencies with ultrahigh efficiency on a microchip. How did they pull it off? By combining dispersion engineering—shaping the way different wavelengths

In mid 2025, Amazon crossed a milestone that would have seemed like science fiction a decade ago: One million autonomous robots are deployed across its logistics operations. It’s a staggering figure—one that illustrates how far automation has come and how quickly it’s spreading. Meanwhile, lawmakers are considering the first federal frameworks for robotics and autonomous

In this episode of Photonics Hot List: Pinhole imaging, one of the world’s oldest image-creating approaches, could someday revolutionize next-generation imaging, thanks to developments by researchers at East China Normal University. Space-based laser communications developer Cailabs is now set to expand, metasurface innovator Metalenz will soon expand its product and patent portfolio, and Lattice Materials

Frequency combs generate spectra with discreet and equally spaced lines—akin to a comb’s teeth. “In short, frequency combs can be viewed as rulers of frequency,” says Qing Hu, a professor of electrical engineering and computer science at MIT, who led the group’s work. Until now, designing frequency combs with the bandwidth required for mass-producible remote
