A method for controlling the spectrum of spontaneous parametric down-conversion has
been implemented. This method is based on the application of the gradient of an
electrostatic field to a nonlinear crystal where down-conversion occurs. Due to the electro-
optical effect, ie, the dependence of the refractive indices on the applied field, the phase-
matching conditions are different along the length of the crystal and, as a result, the
spectrum of the emitted biphoton field is modified.

Abstract
A method for controlling the spectrum of spontaneous parametric down-conversion has been implemented. This method is based on the application of the gradient of an electrostatic field to a nonlinear crystal where down-conversion occurs. Due to the electro-optical effect, i.e., the dependence of the refractive indices on the applied field, the phase-matching conditions are different along the length of the crystal and, as a result, the spectrum of the emitted biphoton field is modified.
