Next-generation optical sensor can read photon spin across UV-to-infrared wavelengths

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not only the intensity and wavelength of light but also its rotational direction-the spin information of photons. The team successfully implemented a quantum-dot-based optical sensor that can detect circularly polarized light (CPL) across an ultra-wide spectral range-from ultraviolet to short-wave infrare...
