    A dark soliton pulse beam that has potential applications in the probing and transport of atoms or molecules as an optical tweezers is demonstrated. The trap pulse beam is formed in the gap between a BP signal at 1500.00 nm and Stokes signal at 1500.09 nm, which have peak powers of -12 dBm. The generated beam is seen to be stable with no fluctuations over a test period of 10 minutes, which is important to ensure that the transported atom / molecule is not lost in the link media. ©2010 IEEE.

    We present the fascinating results of dark soliton pulse array generation using the multilight sources via an optical multiplexer. The dark soliton array with different center wavelengths can be generated. The experimental setup was operated by using the brillouin-enhanced fiber laser scheme, whereas the experimental results of the dark soliton array are generated and achieved. In application, the dark soliton array can be used to form the molecules/atom trapping array, which can be used to form the molecules/atoms memory array for molecular computer and communication. Moreover, the transmission molecules/atoms can be secured by using the dark-bright soliton conversion behaviors. Results obtained have shown that the free spectrum range and the amplified power of 2.1 nm and 20 W of the bright soliton after dark-bright soliton conversion with wavelength center at 1.50 μm can be achieved, respectively. © 2010 Wiley Periodicals, Inc.
