Exploiting engineered second- and third-order nonlinear mixing in tailoring supercontinuum generation in LiNbO3 waveguides

Abstract

We investigate the interplay between the second- and third-order nonlinearities in lithium-niobate waveguides with uniform and linearly-chirped poling. The poling-period is exploited as an additional degree-of-freedom to tailor the output spectrum in an unprece-dented way.
