Abstract
The second-harmonic dependence on the input fundamental light has been measured in optical fibers having a χ(2) induced by seeding. The results are explained with a model that includes self-phase and cross-phase modulation in the equations governing second-harmonic generation and seeding. This leads to an intensity-dependent phase mismatch whose strength also depends on the relative polarizations of the fundamental and second-harmonic lights. During seeding, the same effects result in a χ(2) grating detuned from exact phase matching.
