利用电弧熔接器对多芯光纤进行了二维干涉捕获实验。使用衍射光学元件将光均匀地耦合到所有四个芯中。条纹的可见度和晶格的外观可以通过旋转半波片来改变。因此，可以将颗粒从一维捕获操纵到二维捕获或各种不同的二维布置。排列细菌种群的能力在群体感应、絮凝物和生物膜以及代谢合作研究中具有潜在的应用。
Two dimensional interferometric trapping of multiple microspheres and Escherichia coli has been demonstrated using a multicore fiber lensed with an electric arc fusion splicer. Light was coupled evenly into all four cores using a diffractive optical element. The visibility of the fringes and also the appearance of the lattice can be altered by rotating a half wave-plate. As a result the particles can be manipulated from one dimensional trapping to two dimensional trapping or a variety of different two dimensional arrangements. The ability to align bacterial populations has potential application for quorum sensing, floc and biofilm and, metabolic co-operation studies.
