Incoherently coupled two component screening photovoltaic solitons in two-photon photorefractive materials under the action of external field

摘要: Abstract The existence of incoherently coupled two-component steady state photovoltaic solitons in biased two-photon photorefractive materials due to effect has been investigated. In the regime, these can propagate bright–bright, dark–dark and bright–dark configurations. most important finding is that, with application electric field, it possible generate control them those media where soliton formation was hitherto prohibited. Dynamic evolution examined using numerical simulations, which show that are stable.
