In this episode of Photonics Hot List: NC State researchers have designed and demonstrated a tiny spectrometer that’s showing tremendous promise for a wide range of applications, from biomedical diagnostics to manufacturing. In the business realm, a strategic collaboration in the works is poised to address the growing complexity and performance demands associated with photonic […]

In this second installment of a multipart series, Robin Hawk, an optics and photonics industry pioneer and CEO of Galxyz LLC, talks about the new company and the groundbreaking developments they’re already making, including nuclear diamond-powered photonics platforms. Following the Photons: A Photonics Podcast dives deep into the fascinating world of photonics and optics. Join

Chiral metasurfaces engineered by a team of scientists led by Hatice Altug’s group at the Bionanophotonics Systems Laboratory of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, in collaboration with Yuri Kivshar’s group at the Australian National University (ANU), leverage the interplay between the meta-atom shape and varying the symmetry of its two-dimensional (2D)

Each day, we are fortunate to enjoy the natural beauty of color. While many objects gain their appearance from pigments, butterfly wings, peacock feathers, certain woods, and chameleon skin are brilliant reflectors of specific wavelengths due to the presence of micro-nano-patterned structures. We have much to learn from nature, because similar nanostructures can be adapted

Data-based decisions for cardiovascular diseases Cardiovascular diseases (CVDs) are the leading cause of death worldwide. 20.5 million people died from CVDs in 2021, which represents about one third of all global deaths. Hi-D Imaging is dedicated to measuring and analyzing blood flow characteristics, because these are key indicators of cardiovascular function. Based on its research,

Precise, accurate, and continuous monitoring of gases like carbon dioxide and methane is crucial as we work to combat the effects of climate change and ever-progressing air pollution. Recognizing this, a new European Commission-funded initiative could turn existing optical fiber telecommunications networks into a large-scale distributed sensor. Do you have amazing, cutting-edge systems or products?

Extreme electromagnetic fields are created when electrons within materials vibrate and bounce at high speeds, and Aakash Sahai, an assistant professor of electrical engineering at the University of Colorado Denver, recently came up with a way to make it happen within the lab for the first time. His inspiration stems from a dire need for

This is the first of a multipart series featuring Robin Hawk, a pioneer in the optics and photonics industry who has codeveloped several technologies, including HDTV. She is now CEO of Galxyz LLC, a company she founded with her husband, Dan Hawk, where they’re developing next-generation technologies like nuclear diamond-powered ultraviolet quantum photonics platforms, end-to-end

After years of anticipation, AR glasses are finally reaching a pivotal point. As hardware design evolves to deliver lighter, slimmer, and more comfortable devices, we are on the cusp of making AR truly wearable for everyday life. This breakthrough is driven by the convergence of miniaturized components and scalable manufacturing that enable brands to develop

Galvanometer scanner and optical errors. The galvanometer scanner, while incredibly fast and agile, brings its own set of errors. F-theta lenses, which are used to translate the scanner’s angular motion into a flat focal plane, are not perfect and introduce spatial nonlinearities known as pincushion or barrel distortion (see Fig. 3). Furthermore, the laser beam
