(Phys.org)—Researchers have designed a nanoscale device that, under ideal conditions, can confine a "bit" of light (that is, light with a single precise energy value) for an infinite amount of time. Although a physically ...
(Phys.org) —Optical transistors and switches are fundamental in both classical and quantum optical information processing. A key objective in optics research is determining and developing the structural and performance ...
(PhysOrg.com) -- "Carbon nanotubes have a lot of really nice properties that make them good for photonics," Laurent Vivien tells PhysOrg.com. Ever since the discovery that carbon nanotubes have photoluminescence when encapsulated ...
(Phys.org) -- Ever since its discovery in 2004, graphene, the honey-comb arranged sheet of one atom thick carbon atoms, has continued to make waves in both the physics and engineering worlds. Now comes news from yet another ...
