High-voltage bulk photovoltaic effect and the photorefractive process in LiNbO3
A. M. Glass, D. von der Linde, T. J. Negran- Physics and Astronomy (miscellaneous)
Photocurrents in doped LiNbO3 crystals are shown to be due to a bulk photovoltaic effect with saturation voltages in excess of 1000 V (∼105 V/cm). This effect accounts for the light-induced index changes in LiNbO3. An explanation of the photovoltaic effect, based on the asymmetry of the lattice, is proposed.
