New “all-optical” nanoscale force sensor accesses previously inaccessible environments
Illustration of atomic arrangement within a single lanthanide-doped nanocrystal. Each lanthanide ion can emit light. Credit: Andrew Mueller/Columbia Engineering Mechanical forces are an essential feature of many physical and biological processes. Telemetry of mechanical signals with high sensitivity and spatial resolution is required for a wide range of applications, from robotics to cell biophysics and medicine, and even space travel.…

All-optical switch device paves the way for faster fiber optic communications
Schematic diagram of an optical cavity with a one-molecule-thick layer of tungsten diselenide (WSe2) at the antinode, which is the point of maximum optical field intensity. Credit: Deng Lab, University of Michigan Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber optic cables, but currently optical signals become a bottleneck when data processing…
