In 1975, three CERN theorists, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos, undertook the first comprehensive study of the collider phenomenology of the Higgs boson. Almost 40 years later, it was discovered at the ...
Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective and high-performance lidar (or light detection and ranging) systems. Lidar, which uses laser pulses ...
One of the main objectives of optics is the control of light propagation and confinement. Progress in optics historically started with the development of bulky lenses and mirrors, then prisms and gratings, and so on. The ...
Holographic interferometry is the technique of measuring stress, strain, and vibration with light. It is defined by the wavelength of light, finding flaws in structural bonds. It makes full use of a hologram's ability to ...
A new publication in Opto-Electronic Advances overviews dynamic metasurfaces and metadevices empowered by graphene.
Nature may abhor a vacuum, but it sure loves structure. Complex, self-organized assemblies are found throughout the natural world, from double-helix DNA molecules to the photonic crystals that make butterfly wings so colorful ...
Today's society generates ever more internet data traffic for applications such as ultra-high-definition video, cloud services and 5G mobile connections. This decades-long continual exponential growth of data traffic has ...
Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...
A newly proposed technique enables rapid 3D image acquisition. One-scan is a technique involving an elongated light spot that resembles a "needle" which captures three-dimensional (3D) images of a specimen.
Weak optical signals are common in many science and technology applications. However, they are difficult to detect or process due to the incoherent noise that is inherently present in any system. Ph.D. student Benjamin Crockett ...
