The potential well stability is generated and achieved when the system is controlled by the Gaussian pulse via a control port. The dynamic multi-tweezers can be generated, which can be available for molecule/atom trapping and transportation sources. © 2010 Published by Elsevier Ltd.

Introduction Dark-bright soliton control within a semiconductor add/drop multiplexer has shown the promising applications, which has been investigated clearly by the authors in references [1, 2]. One of the advantages is that the dark soliton peak signal is always at a low level, which is useful for secured signal communication in the transmission link. The other is formed when the high optical field is configured as an optical tweezer or potential well [3, 4], which is available for atom/molecule trapping. In principle, an optical tweezer uses forces exerted by intensity gradients in a strongly focused beam of light to trap and move a microscopic volume of matter. Therefore, optical tweezers technique has become a powerful tool for manipulation of micrometer-sized particles in three spatial dimensions. Initially, the useful static tweezer is recognized, and the dynamic tweezer is now realized in practical work [5-8]. Recently, Schulz et al [9] have shown that the transfer of trapped atoms between two optical potentials could be performed. * Corresponding author. Tel.: +6-689-445-2224; fax: +6-627-227-262.
