Recently, researchers have been developing a new type of laser that combines photons and plasmons (electron density oscillations) into a single radiation-emitting device with unique properties. In particular, nanoscale photon-plasmon ...
(Phys.org)—Physicists have built a nanowire cage that blocks one or more wavelengths of light from either entering or escaping, yet allows liquids and gases to pass through the small gaps between the nanowires. The "optical ...
(PhysOrg.com) -- Although lasers come in all shapes and sizes, one of the most recent laser designs is especially intriguing, since it’s made of just a single nanowire. Due to its small size and simplicity, the single-nanowire ...
Contrary to the tremendous success story of electronic integration, photonic integration is still in its infancy. One the most serious obstacles it faces is the need to use a variety of materials to achieve different functions—unlike ...
