Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. The different colors are emitted from different parts of the quantum dot—red from the core, green from ...
(PhysOrg.com) -- “Quantum wells have been instrumental in telecommunications, enabling light amplification,” Patanjali Kambhampati tells PhysOrg.com, “but theory has suggested that a very small - colloidal - quantum ...
A team led by University of Utah physicists has discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. The never-before-seen phenomenon will be important for an emerging ...

(PhysOrg.com) -- “People are interested in the mid-infrared,” Dan Wasserman tells PhysOrg.com. Infrared light has a wavelength longer than visible light, and many molecules have numerous very strong optical resonances ...
In an advance that sounds almost Zen, researchers at the National Institute of Standards and Technology and JILA, a joint institute of NIST and the University of Colorado at Boulder, have demonstrated a new type of pulsed ...
