Phase-matched second-harmonic generation in novel corona poled glass waveguides

Abstract

Second-order optical nonlinearity χ(2) is induced in glass films by corona poling. The glass films are fabricated by radio-frequency sputtering Corning7059 onto Pyrex glass substrates. The values of second-order nonlinear coefficient d33 of the corona-poled glass films are estimated to be ∼0.5 pm/V. Using the corona-poled glass films as a waveguide, phase-matched second-harmonic generation has been demonstrated in the glass films for the first time. The origin of the χ(2) is considered to be related to the defects in the glass films.
