Nonlinear waveguide chip (IMAGE) Optica Caption Chip-based nanophotonic nonlinear waveguides were a key component in this new system because they allowed very efficient conversion of light from one wavelength to another to create the supercontinuum. A close up of the nonlinear waveguide chip is shown here. Credit David R.
