Follow along as Machine Design interviews John Ellis, an entrepreneur, inventor and founder of Massachusetts-based engineering consulting firm Optics for Hire. The Optics for Hire team—a group of ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

By harnessing two natural timescales in resonator arrays, researchers created photonic chips that reliably produce multiple harmonics without active compensation. For decades, scientists and engineers ...
