We demonstrate experimentally wavelength tuning of second-harmonic generation in
waveguides induced by photorefractive solitons in a KNbO3 crystal. By rotating the crystal …

We demonstrate experimentally second-harmonic generation in waveguides induced by
photorefractive solitons and show that the conversion efficiency is improved considerably …

We demonstrate self-trapping of one-dimensional and two-dimensional optical beams in a
photorefractive KNbO_3 crystal. We study the waveguides induced by the self-trapped …

Second-harmonic generation in a photorefractive crystal is investigated. It is shown that a
fundamental wave that is not in the photorefractive regime can be locked onto a second …

Photorefractive one-transverse-dimensional bright solitons are studied in KNbO3 crystals. A
quantitative condition defining when an experimental beam can be considered as a soliton …

Optical spatial solitons1 in photorefractive crystals2 have shown potential to form graded
index waveguides which can guide other beams. 3, 4 A soliton forms when a photoinduced …

We report what we believe is the first experimental observation of bright-soliton-induced two-
dimensional waveguides. The waveguides are induced by two-dimensional photorefractive …

A photorefractive crystal waveguide with periodically reversed c axis (PCW-PX) is proposed
for enhanced photorefractive two-wave mixing. In PCW-PXs, only the guided modes which …

We report the observation of large self-deflection of 2-D bright photorefractive solitons in
LiNbO_3 crystal under a dc applied field. Beam deflection as large as 300?? m after a 7 mm …

We report the observation of high-intensity solitons in a bulk strontium barium niobate
crystal. The solitons are observed by use of 8-ns optical pulses with optical intensities …
