Separate holographic-Hamiltonian screening soliton pairs in a biased series photorefractive crystal circuit
有外加电源的串联光折变晶体回路中的独立空间全息-哈密顿屏蔽孤子对

Separate holographic-Hamiltonian screening soliton pairs are predicted in a biased series photorefractive crystal circuit consisting of two photorefractive crystals connected electronically by electrode leads in a chain with a voltage source. The existence of four types of the separate soliton pairs:dark-dark, bright-dark, dark-bright and bright-bright, in such a circuit is proved. Under the limit that the spatial extent of the optical wave is much less than the width of the crystal, the Hamiltonian dark soliton can affect the other soliton by the light-induced current whereas the Hamiltonian bright soliton and holographic soliton cannot affect the other soliton in the soliton pair.
