Large second-order optical nonlinearity in Ge-doped silica glass induced by simultaneous applications of a high DC voltage and UV irradiation 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.
