Photorefractive steady state solitons up to telecommunication wavelengths in planar SBN waveguides

Abstract

We experimentally demonstrate strong photorefractive self-focusing and soliton formation in Rh-doped strontium-barium niobate waveguides at telecommunication wavelengths up to lambda = 1.5 mum. A comparison of soliton formation at different wavelengths in the visible and infrared region is carried out. We measure the electrooptic coefficient r(33), analyze the soliton width, the accessible intensity range, and the wavelength dependence of the so-called `dark intensity'.
