Advancements in Diffraction Grating Aim to Change the Rules Because they separate light into its spectral components, diffraction gratings lie at the heart of modern spectrometers, hyperspectral imagers, optical coherence tomography systems, and similar instruments. In the future, gratings may improve automotive lidar, a market that could reach tens of millions of units annually. Gratings have also played a role in reducing the footprint of spectrometers...

Editorial
Elevate, advocate, repeat Deriding the uneasy relationship between science and politics makes for good sport and offers almost as much smug satisfaction as mocking congressional inefficiency. But science and politics are deeply entangled in practice, and often in purpose. The preceding year gave the scientific community ample opportunity to roll its eyes at the usual congressional dithering, partisanship, and...

EPIC Insights
Creative Fabrication Yields a Phase Shift for Diffractive Optics Whether they take the shape of Fresnel lenses and spirals — or something resembling topographical maps, peacock features, or hyperbolas — diffractive optical elements (DOEs) are designed to introduce a particular phase shift to incoming light to create a desired phase profile of the outgoing beam. They are vital components that find use in a broad range of applications, including beam shapers for...
