Phys. Rev. Lett. 85, 748–751 (2000)Interaction of Localized Structures in an Optical Pattern-Forming SystemReceived 22 March 2000; published in the issue dated 24 July 2000 We report on the observation and interaction of dissipative localized structures in an optical pattern-forming system. Single localized structures are found to have oscillatory decaying tails originating from diffraction. We observe bound states of two or more constituents. These clusters contain several preferred mutual distances. Numerical simulations show that the corresponding interactions are mediated by the oscillatory tails. © 2000 The American Physical Society URL:
