Some of the most vibrantly colored creatures in the animal kingdom don't owe their amazing colors to pigment. Instead, they cover themselves with microscopic structures that fine tune the way they reflect light. Now, these animals are inspiring a new generation of nanotechnology. Understanding why these structures occur in nature, and how we ...
Courtesy: ICFO A new technique for imaging single molecules that does not rely on fluorescent emitters could find a host of applications in nanotechnology, photonics and photovoltaics. The technique, which was developed by researchers in Barcelona, works by detecting stimulated emission from single quantum dots at room temperature. Its speed ...
Though this interaction is only significant on very short length scales, it could have profound implications for the design of computer chips and other nanoscale electronic components where heat dissipation is key. It also upends what many of us learned about heat transfer in high school physics. “Heat is usually conducted in a solid through ...

NTT and Tokyo Tech developed an all-optical switch operating in the ultrafast regime (less than one picosecond) with low energy consumption by combining an extremely small optical nanoscale waveguide based on plasmonics4 with graphene (Fig. 2a). The main points are as follows. [1] Enhancement of absorption and nonlinear optical effect5 in ...
Scientists from Oxford University, in collaboration with researchers at the universities of Münster and Exeter, have created and demonstrated the "first ever integrated nanoscale device which can be programmed with either photons or electrons". This ...
