In the present paper we review the physics of soliton formation in lithium niobate by means of photorefractive nonlinearity. Considering the waveguides that such solitonic beams leave …
We experimentally demonstrate the writing of soliton waveguides in lithium niobate with blue violet light, at λ= 405 nm. This wavelength, obtained from a low-cost laser diode, allows very …
