The photorefractive soliton as an electro-optic modulator

Summary form only given. We discuss how to fabricate an electro-optic modulator in SBN using a permanent two-dimensional single-mode waveguide impressed into a crystalline lattice by a real-time photorefractive soliton. After fixing the waveguide, we investigate the effect of the induced waveguide on the soliton polarization by using an 840 nm probe laser beam. An ordinary-polarized probe beam is launched to the SBN crystal. At the output side a polarizer at the crossing position is set so that the output beam is almost completely blocked without applying an external voltage. This configuration serves as the basis of the electro-optic amplitude modulation of light.
