Yale scientists have found a way to greatly boost the intensity of light waves on a silicon microchip using the power of sound.
Terahertz radiation—the band of electromagnetic radiation between microwaves and visible light—has promising applications in security and medical diagnostics, but such devices will require the development of compact, ...
Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto lenses so long.
Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic "fingerprints" of a wide range of ...
Physicists from Trinity College Dublin's School of Physics and the CRANN Institute, Trinity College, have discovered a new form of light, which will impact our understanding of the fundamental nature of light.
Holograms are a ubiquitous part of our lives. They are in our wallets—protecting credit cards, cash and driver's licenses from fraud—in grocery store scanners and biomedical devices.
Researchers in the School of Engineering & Applied Science at Washington University in St. Louis have discovered a novel route to encode chaos on light in an optomechanical microresonator system.
Introducing the disposable laser: Ultra-low-cost, easy to fabricate 'lasing capsules' made with inkjet printer
Since lasers were invented more than 50 years ago, they have transformed a diverse swath of technology—from CD players to surgical instruments.
Work by an internationally renowned University of Rochester professor may offer an alternative to the way in which researchers have approached some photonics applications.
Converting a single photon from one color, or frequency, to another is an essential tool in quantum communication, which harnesses the subtle correlations between the subatomic properties of photons (particles of light) to ...
