  • Method and apparatus for creating large second-order nonlinearities in fused silica
    Patent number: 5239407
    Abstract: A large second-order nonlinearity (.chi..sup.(2) .about.1 pm/V.about.0.2 .chi..sup.(2).sub.22 of LiNbO.sub.3) is induced in the near surface (.about.4 .mu.m) region of commercial fused silica optical flats by a temperature (250.degree.-325.degree. C.) and electric field (E.about.5.times.10.sup.4 V/cm) poling process. Once formed, the nonlinearity is roughly 10.sup.3 -10.sup.4 larger than that found in fiber second-harmonic experiments and is very stable at room temperature and laboratory ambient. The nonlinearity can be cycled by repeated depoling (temperature only) and repoling (temperature and electric field) processes.
