A large second-order nonlinearity in Ge-doped silica glass induced by simultaneous applications of a high DC electric field and ultraviolet irradiation (UV-poling) is reported. The nonlinearity thus induced has been found to be quite relevant to the GeE′ center. The d coefficient so far obtained exceeds the second biggest d-tensor component of LiNbO3.
