Photorefractive dark solitons as waveguides

Not Accessible

Your library or personal account may give you access


Recently, we reported on the prediction1,2 and observation3 of a new type of spatial soliton. For this new spatial soliton, compensation for diffraction is accomplished through the photorefractive effect. In this case, a Gaussian beam incident on a photorefractive crystal is trapped at a diameter of about 30 μm and propagates through the crystal while maintaining its spatial shape and defying the rules of diffraction. We have referred to our observation as a photorefractive bright soliton.
