Paper Abstract

The spatial solitons can create reversible or irreversible single-mode waveguides in the propagating materials. The important features are the 3D orientation and graded index profile matched to the laser fundamental mode. Bright spatial solitans are theoretically demonstrated and experimentally observed in the propagation of laser beams in widely available photorefiactive crystals such as Bi12 (BSO) and LiNbO3 (LN). We show the first observation of waveguiding by screening-photovoltaic bright solitons in LN and the low absorption and dispersion of the corresponding light produced waveguides (with femtosecond laser pulses). Applications in high coupling efficiency, adaptive optical interconnections and photonic crystal production are possible.
