For two decades, terahertz technology carried the promise of nondestructive, material-specific insights but remained primarily confined to research labs. The scientific community was impressed with demonstrations of nondestructive, label-free probing through polymers, coatings, and tablets, resolving structures on picosecond timescales, and detecting spectral fingerprints of water and other materials. But the systems were large, alignment-sensitive,

A new diode nanocavity created by a team of researchers at Simon Fraser University (SFU) and quantum company Photonic Inc. in Canada enables optical and electrical control of silicon “color center” qubits. Until now, these qubits, a.k.a. T centers, were controlled optically with lasers. This dual control option of T centers hints at potential applications

Light is the fastest and cleanest carrier of information we know. The science and technology of guiding, manipulating, and detecting light—photonics—underpins every facet of modern life, from the global internet and medical imaging to precision manufacturing and autonomous sensing. For decades, the photonics industry has flourished in an environment of predictability. Much of linear optics

In this episode of Photonics Hot List: Researchers in Portugal have designed an imaging approach that distinguishes between benign and malignant tumors, and could ultimately help clinicians develop more effective treatments. The business sector of the photonics industry is booming with the recent announcements of several mergers and acquisitions. A so-called photonic crystal highway, guiding

A team of researchers led by Professor Anita Ho-Baillie, the John Hooke Chair of Nanoscience at the University of Sydney in Australia, set a new solar technology record for the world’s largest triple-junction perovskite-perovskite-silicon tandem solar cell. Their 16-cm2 triple-junction cell features a steady-state power conversion efficiency of 23.3% (independently certified), which is the highest
