Paper Abstract

We report soliton waveguide creation in lithium niobate crystals with 405nm c.w. radiation from a low-cost blue-violet laser diode. The high photorefractive sensitivity of lithium niobate at this wavelength allows fast soliton waveguide writing with low light power (~40nW). The writing process of soliton waveguides at this wavelength is experimentally studied. We also show the convenient writing of soliton waveguides arrays in the crystal volume and the good propagation of femtosecond pulses (at 1030 nm) through these waveguides. These waveguides are good candidates for all-optical integrated photonics.
