A new class of quantum dots deliver a stable stream of single, spectrally tunable infrared photons under ambient conditions and at room temperature, unlike other single photon emitters.
Columbia Engineering researchers report the first nanomaterial that demonstrates “photon avalanching,” a process that is unrivaled in its combination of extreme nonlinear optical behavior and efficiency. The realization of photon avalanching in nanoparticle form opens up a host of sought-after applications, from real-time super-resolution optical microscopy, precise temperature and environmental sensing, and infrared light detection, to optical analog-to-digital conversion and quantum sensing.
A team of researchers co-led by Berkeley Lab and Columbia University has developed a new material called avalanching nanoparticles that, when used as a microscopic probe, offers a simpler approach to taking high-resolution, real-time snapshots of a cell’s inner workings at the nanoscale.
Researchers at Berkeley Lab played a key role in an analysis of data from the world’s largest particle collider that found proof of rare, high-energy particle interactions in which matter was produced from light.
SUMMARYResearchers discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform. Using this method, coined strainoptronics by a team led by George Washington University professor Volker Sorger, the researchers demonstrated…
The study introduces a generic way of engineering artificial forces between photons and molecules to enable new energy transfer pathways between molecules.
If a photon source could be placed on a single chip and made to produce photons at a high rate, this could enable high-speed quantum communication or information processing. In Applied Physics Reviews, a simple on-chip photon source using a hyperbolic metamaterial is proposed, and investigators carried out calculations to show that a prototype arranged in a precise way can overcome problems of low efficiency and allow for high repetition rates for on-chip photon sources.
A team of quantum researchers from ORNL have conducted a series of experiments to gain a better understanding of quantum mechanics and pursue advances in quantum networking and quantum computing, which could lead to practical applications in cybersecurity and other areas.
