Large quadratic modulation instability gain in nanophotonic lithium niobate
We exploit quadratic modulation instability in a periodically poled lithium niobate nanophotonic waveguide to achieve broadband optical amplification. A high on-chip gain exceeding 18 dB is obtained with a pump peak power below 1.5 W.
