A wavelength of visible light is about 1000 times larger than an electron. Because of the difference in scale, the interactions between photons and electrons are inherently weak. MIT researchers have found that photonic flatbands can overcome the dimensionality mismatch between photons and electrons and significantly strengthen light-electron interactions. Their experimental results support the use of flatbands as test beds for developing strong light-electron interactions and efficient, compact, free-electron light sources. The underlying principle of flatbands involves the...Read full articleRelated content from Photonics MediaARTICLESResearchers Increase Spatiotemporal Resolution of Imaged LightwavesA team of physicists from the Max Planck Institute of Quantum Optics and the Ludwig Maximilian University of Munich, in cooperation with Stanford University researchers, have developed a technique to...Photonics Spectra September 2022 IssueLight Beam Observation Extends Beyond Spectrum of DisorderResearchers from the University of Rostock and the Technion - Israel Institute of Technology demonstrated a mechanism that prevented lightwaves from spreading freely.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookVibration Control: Limiting Mechanical Noise: Vibration control plays a critical role in research and industry. Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookMachine Vision Cameras: Making the Right Selection: Improvements and affordability have broadened the use of vision systems for inspection, but several factors should be considered before making a purchase.Technological advances have resulted in new, higher-quality sensors that enable machine vision cameras to deliver greater features and functionality at a lower cost than ever before.
