Opto-mechanical non-reciprocity in fiber

The internet era that we live in depends completely on the transfer of vast amounts of information over optical fibers. Optical fibers are literally everywhere. In fact, the overall length of optical fibers installed on our ...

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 ...

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 ...

Blocking cellular communication stops SARS-CoV-2

In the transmission of signals within the cell which, for example, stimulate cell growth or trigger metabolic processes, phosphate groups play an important biochemical role. The phosphate groups are often attached to proteins ...
