Graphene found to emit infrared light
Engineers find a way to win in laser performance by losing
Energy loss in optical systems, such as lasers, is a chief hindrance to their performance and efficiency, and it occurs on an ongoing, frustrating basis.
Researchers get better metrics on laser potential of key material
Researchers from North Carolina State University have developed more accurate measurements of how efficiently a polymer called MEH-PPV amplifies light, which should advance efforts to develop a new generation of lasers and ...
A silicon chip with integrated laser and optical grating offers new possibilities for telecommunications
(PhysOrg.com) -- Silicon is an ideal platform for integrated photonic circuits because the material is cheap and readily available. Silicon chips with an integrated laser source capable of emitting light at ...
Ultra fast optical amplifier: Silicon and erbium on one chip for the first time
Within optical microchips, light finds its way through channels, waveguides, made of silicon. Light from a glass fiber, for example, is led through a structure of optical channels with splitters and couplers. ...
