On the Mechanisms of Coherent Photovoltaic Effect for Second Harmonic Generation in Glass Fibers,
Abstract
Different models have been suggested for photoinduced second-harmonic generation in silica fibers. The model with charge carriers redistribution in the core of the fiber due to coherent photovoltaic effect was proposed in. The coherent photovoltaic effect means that direct current appears in the glass under coherent pump and second-harmonic light waves. Theory of this effect was proposed in but, the expressions presented there are too complicated to get estimations of photocurrent and also the semiclassical method used there is not adequate to the phenomena. One of the possible mechanism of such effect was proposed in but there is no consistent calculation of the photocurrent. So, the question on the microscopic mechanism of coherent photovoltaic effect is still open.
