Researchers create dispersion-assisted photodetector to decipher high-dimensional light

A new study published in Nature, conducted by an international collaboration team led by Prof. Wei Li from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences, introduces a novel miniaturized photodetector capable of characterizing arbitrary polarization states across a broadband spectrum with a single device and a single measurement.
