a b s t r a c tIn this paper we have presented a theoretical investigation on the propagation properties of incoherent solitons in photorefractive media which is characterized by noninstantaneous saturating nonlinearity. Using mutual coherence function approach, we have obtained the equation of existence curve for such solitons. We have discussed the coherence characteristics of these solitons. We have found that solitons with a particular radius can possess two different critical powers. The dynamical evolution of these solitons has been discussed in detail by both analytical and numerical simulation.

“…The spatial profile, dynamical evolution and self deflection of the soliton in one crystal can affect the spatial profile, dynamical evolution and self deflection of the soliton in the other crystal, hence the solitons are said to form a separate coupled pair. Such separate coupled soliton pairs have been studied in typical PR media [33][34][35][36][37][38][39][40][41][42][43][44].…”

We present, for the first time a theoretical foundation for separately coupled solitons in a biased series circuit consisting of semi-insulating photorefractive multiple quantum well (MQW) waveguides. As an example, a slab semiconductor waveguide based on a GaAs/AlGaAs structure is considered. The coupled steady state space charge field is derived for both the MQW structures using a bipolar band transport model. Hence, a system of two coupled equations is obtained for each MQW structure which governs the dynamical evolution of light beams. We then prove the existence of dark-dark, grey-grey and grey-dark separately coupled soliton pairs. We also see that the soliton propagating individually in one PR semiconductor can affect the other by the light-induced current. We investigate this coupling effect with respect to the soliton beam's intensity profile and for each of the three cases, namely, dark-dark, grey-grey and grey-dark separately coupled solitons. Some potential applications are discussed.

“…Each crystal can support a spatial soliton. Recently, Ji et al [13,14] pointed out that separate spatial soliton pairs can also exist in a series circuit consisting of two PR crystals with the two-photon PR effect [15,16].…”

Grey–grey separate spatial soliton pairs are predicted in a biased series circuit consisting of two centrosymmetric photorefractive (PR) crystals with the two-photon PR effect. The numerical results show that two grey solitons in a soliton pair can affect each other by the light-induced current. The effects of the intensity of solitary waves and gating lights on the normalized profiles and the dynamical evolutions of solitons are discussed.
