What is the difference between linear chains and rings composed of the same material? The molecular building blocks are identical, but from a mathematical point of view the structures have distinct ...

Molecular engineering strategies can be used to develop new features in nonlinear optical systems. Self-assembly based on chiral molecules is one important approach that opens up interesting routes in ...

Feature issue of the Journal of the Optical Society of America B provides '...an overview of the field that is attentive to constraints imposed by real materials and focuses on the efficiency of the ...

A standard digital camera used in a car for stuff like emergency braking has a perceptual latency of a hair above 20 milliseconds. That’s just the time needed for a camera to transform the photons ...

Fig. 1. (a, b) Two- and three-pulse sequences with a near-infrared pulse generating electrons (orange), a THz probe pulse (blue), and a perturbing THz pulse (green). The pulses are shown along the ...
