New Sensor Materials and Designs Deepen SWIR Imaging Capabilities Imaging in the shortwave infrared (SWIR) range, from 1000 to 2500 nm, offers significant new advantages in an array of applications, from autonomous vehicles to food quality inspection. SWIR photons are scattered less by dust or fog than shorter-wavelength light, for example, which allows cameras operating in this range to provide visual data for advanced driver assistance systems and...
PICs Set Their Sights Beyond Data and Telecom Due to the strong association that photonic integrated circuits (PICs) have with the data and telecom markets, it is easy to overlook their potential in other verticals — such as health care,...

Editorial
It’s the thought that counts It is poor form to compare the largesse of the recent gift-giving season against that of past holidays. Hopefully, the rules are more forgiving when comparing scientific discoveries. As rumors mounted last month about a major breakthrough in laser fusion, there was time to contemplate how the looming announcement might stack up against the launch of the James Webb Space Telescope that had...
