Optics & lasers as a research area encompasses the fundamental and applied study of the generation, propagation, manipulation, and detection of light, with a particular emphasis on coherent and monochromatic radiation from lasers. It includes laser physics (gain media, optical cavities, nonlinear and quantum optical effects), beam shaping and guiding (waveguides, fibers, integrated photonics), optical materials and devices (mirrors, modulators, detectors), and advanced techniques such as ultrafast optics, high-power and high-intensity laser systems, laser spectroscopy, and laser-based metrology. This field underpins technologies in precision measurement, optical communication, imaging, microfabrication, and control of matter with light.
In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric photonic-crystal surface-emitting laser ...
