Comb of a lifetime: A new method for fluorescence microscopy

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific ...

Temporal control of light echoes

Scientists at Paderborn University, the Technical University of Dortmund and the University of Würzburg have for the first time used laser pulses to precisely control photon echoes, which can occur when light waves superimpose ...

Physicists make electrical nanolasers even smaller

Researchers from the Moscow Institute of Physics and Technology and King's College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported ...

New light amplifier can boost the potential of photonics

A new light amplifier developed at the University of Twente not only boosts the light signals on a photonic chip, but it also enhances the applicability of those chips. Thanks to stronger light signals, detector chips for ...

Nanodots made of photovoltaic material support waveguide modes

Antimony sulfide, or stibnite (Sb2S3), has been investigated intensively in recent years as a promising material for nontoxic, environmentally friendly solar cells. It is now possible to fabricate thin photovoltaic films ...

Quantum exciton found in magnetic van der Waals material

Things can always be done faster, but can anything beat light? Computing with light instead of electricity is seen as a breakthrough to boost computer speeds. Transistors, the building blocks of data circuits, are required ...

New discovery advances optical microscopy

New Illinois ECE research is advancing the field of optical microscopy, giving the field a critical new tool to solve challenging problems across many fields of science and engineering including semiconductor wafer inspection, ...
