Spectro-temporal representation of femtosecond pulse patterns, prepared by a photonic chip to seed the generation of supercontinuum. The patterns are optimized via machine-learning to select and enhance desired properties in the output supercontinuum. Here, the pulses are separated by 1 picosecond, and measured experimentally via frequency-resolved optical gating (FROG). CREDIT Benjamin Wetzel

Researchers take control of light properties

Scientists can now possibly customize the properties of broadband light using machine-learning and an integrated photonic chip. Also called "supercontinuum", these sources are at the...
