Measurement of χ(2) symmetry in a poled fiber
Optics letters, 2010•opg.optica.org
We measure the values of individual χ^(2) tensor components in a birefringent periodically
poled silica fiber through spectrally separated type I and type II second-harmonic
generation. We demonstrate that the χ^(2) tensor symmetry is consistent with that of χ^(3) in
silica and thereby provide experimental evidence that this χ^(2) originates from a χ^(3)
process.
