Abstract

Rf sputtered multi-component glass films on pyrex substrates exhibited novel quadratic optical nonlinearity by corona poling which was applied for the second harmonic generation in blue-green range¹⁾²⁾. Maker fringe method proved that d₃₃ values of the films was up to 0.6 pm/V at appropriate sample preparation condition. Resistivities of substrate glasses remakably related to efficient poling. Borate component of multi-component glasses gave some effects to establish the quadratic nonlinearity coming from macroscopically noncentrosymmetric structure of the films. Also boudary situations and combinations of each layers gave influences to decay of the nonlinearity.
