    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.

    The calibration system was developed for golf shaft fitting to the club or blade. The system provided the best line and angle of golf shaft to fit into the club slot. This yielded the best controlling for the impact point between the club and the golf ball, including obtained the minimal swaying of golf shaft after the club hit to the ball. The proposed system was consisted of two components: the hardest line tuning and the best line calibration tool. The hardest line tuning was applied to search for the line that indicated the most strongest of the shaft, which contributed the minimal bend within the given certain forced pressure. The best line calibration tool was employed to determine the best angle for fitting the shaft to the golf club which reflected the minimal swaying while hitting to the ball. In this manner, the golfers could control the desired range and direction of the ball. © 2010 Published by Elsevier Ltd.

    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.

The trapped pulse beam is formed in the gap between a BP signal at 1500.00 nm and Stokes signal at 1500.09 nm, which has peak powers of -12 dBm. The generated beam is seen to be stable with no fluctuations over a test period of 10 min, which is important to ensure that the transported atom/molecule is not lost in the link media, therefore, the dynamic optical tweezers are now plausible. The theoretical background of the trapped atom/molecule is also analyzed and described in details. The atomic/molecular network via a wavelength router is also described. © 2010 Elsevier GmbH All rights reserved.

    Enhanced WDM using a Gaussian pulse within a nano-waveguide

    The new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. The Results obtained have shown that more available wavelength bands from the different center wavelengths can be generated, which can be used to form new dense wavelength division multiplexing bands. The novelty of the work is that the expansion of communication bands, especially, when the center wavelengths at 400 and 1,400 nm can be obtained by using a common laser pulse, whereas the amplified and non-dispersive light source can be formed. ©2010 IEEE.
