Physics World Optics & Photonics Briefing 2020
Inside this free-to-read Optics & Photonics Briefing we find out about the interdisciplinary research around optical metamaterials, which are thinner and lighter than traditional lenses. They are being used in a variety of ways: to banish chromatic aberration, filter out undesirable wavelengths, dynamically change the profile of a laser beam, and undercut the diffraction limit. Other articles focus on exciting cross-disciplinary developments in the field of quantum optics. We also talk to a company that uses lasers to create microscopic marks inside gem-quality diamonds and other transparent materials. Elsewhere, researchers are using hollow-core photonic crystal fibres for monitoring air pollution.
