    Title:Ultrafast all-optical switching in nanoplasmonic waveguide with Kerr nonlinear resonator
    Author(s):Lu, Hua(1); Liu, Xueming(1); Wang, Leiran(1); Gong, Yongkang(1); Mao, Dong(1)
    Source: Optics Express  Volume: 19  Issue: 4  DOI: 10.1364/OE.19.002910  Published: February 14, 2011  
    Abstract:A novel ultrafast all-optical switching based on metal-insulatormetal nanoplasmonic waveguide with a Kerr nonlinear resonator is proposed and investigated numerically. With the finite-difference timedomain simulations, it is demonstrated that an obvious optical bistability of the signal light appears by varying the control-light intensity, and an excellent switching effect is achieved. This bistability originates from the intensity-dependent change induced in the dielectric constant of Kerr nonlinear material filled in the nanodisk resonator. It is found that the proposed all-optical switching exhibits femtosecond-scale feedback time. ? 2011 Optical Society of America.

    Abstract:Generation technology of high-power tunable picosecond fiber laser based on the gain switch laser diode and Yb-doped fiber amplifier was experimentally studied. A gain switch laser diode was adopted as the seed source, and a multi-stage single mode Yb-doped fiber preamplifier was combined with two large mode area double-clad Yb-doped fiber main amplifiers to construct the amplification system. The gain compensation technology, tunable filter technology, Sagnac loop technology and cladding pump technology were also used in the high-power tunable fiber picosecond laser system.

    Source: Laser Physics  Volume: 21  Issue: 6  DOI: 10.1134/S1054660X1111020X  Published: June 2011  
    Abstract:We report on the evolution of dissipative-soliton laser from single pulse to soliton molecule, lastly to multiple pulses. The experimental observations show that the pulse separation of soliton molecules is oscillating stochastically. It is found that the proposed fiber laser delivers pulses from a soliton to a soliton molecule, two solitons, a soliton molecule together with a soliton, and three solitons, respectively, when, the pump strength is enhanced gradually. ?

    Title:Error-free OTDM demultiplexer using the supercontinuum spectrum-slicing induced clock signal
    Author(s):Feng, Huan(1); Zhao, Wei(1); Yan, Shuangyi(1); Xie, Xiaoping(1)
    Source: Optics Communications  Volume: 284  Issue: 19  DOI: 10.1016/j.optcom.2011.05.027  Published: September 1, 2011  
    Abstract:We experimentally demonstrate an 80-Gb/s optical time-division multiplexing (OTDM) demultiplexing system based on the cross-phase modulation (XPM) effect in high-nonlinearity fibers. The message carried by OTDM signal is loaded onto the probe signal by sampling the OTDM packet with a 10-GHz stable and controllable clock pulse train. The clock signal with ~ 11 ps pulse width is achieved by employing supercontinuum spectrum-slicing technique, which is distinct from that based on mode-locked lasers. The demultiplexed signal is obtained by filtering out the XPM-induced spectral sidebands of the probe signal. The OTDM demultiplexer based on this novel technique shows excellent performances and contributes to a bit error rate of as low as 10-9. ? 2011 Elsevier B.V.

    Title:Mathematical representation and experimental generation of cylindrical vector beams
    Author(s):Duan, Tao(1); Jin, Pengcheng(1); Li, Chunfang(1)
    Source: Chinese Optics Letters  Volume: 9  Issue: SUPPL. 1  DOI: 10.3788/COL201109.S10602  Published: June 2011  
    Abstract:Cylindrical vector beams are described by the representation formalism of finite electromagnetic beams in free space. This is achieved by factorizing the field vector into a mapping matrix and a Jones-like vector. The vectorial property of a finite beam can be described by a degree of freedom of the mapping matrix that can be determined by the azimuthal angle of a fixed unit vector with respect to the wave vector. In addition, it is a simple and flexible experimental device for converting linearly polarized light beams into cylindrical vector beams. The radially or azimuthally polarized beam is easily converted into either one of these by varying the applied voltage. ? 2011 Chinese Optics Letters.

    Title:Tunable multi-channel wavelength demultiplexer based on MIM plasmonic nanodisk resonators at telecommunication regime

    Source: Optics Express  Volume: 19  Issue: 4  DOI: 10.1364/OE.19.003513  Published: February 14, 2011  
    Abstract:The tunable multi-channel wavelength demultiplexer (WDM) based on metal-insulator-metal plasmonic nanodisk resonators is designed and numerically investigated by utilizing Finite-Difference Time-Domain (FDTD) simulations. It is found that the channel wavelength of WDM is easily tuned by changing the geometrical parameters of the structure and the material filled in the nanodisk resonator. The multi-channel WDM structure consisting of a plasmonic waveguide and several nanodisk resonators increases the transmission up to 70% at telecommunication regime, which is two times higher than the results reported in a recent literature [Opt. Express 18, 11111(2010)]. Our WDM can find important potential applications in highly integrated optical circuits. ? 2011 Optical Society of America.

    Title:Influence of the initial chirp on the supercontinuum generation in silicon-on-insulator waveguide
    Author(s):Wen, J.(1); Liu, H.(1); Huang, N.(1); Sun, Q.(1); Zhao, W.(1)
    Source: Applied Physics B: Lasers and Optics  Volume: 104  Issue: 4  DOI: 10.1007/s00340-011-4496-1  Published: September 2011  
    Abstract:We propose a practical method to broaden the bandwidth of supercontinuum generated in silicon-on-insulator (SOI) waveguide by controlling the initial chirp of inputting femtosecond pulses, which has the main impact on the initial stage of the spectral broadening caused by the self-phase modulation (SPM) effect. The numerical results show that the bandwidth and flatness of the supercontinuum generated in SOI waveguide are sensitive to the initial chirp of inputting femtosecond pulses, the supercontinuum bandwidth can be remarkably enhanced by inputting positive chirp femtosecond pulses with a decreased propagation distance required by soliton fission, and the maximum bandwidth of supercontinuum can be increased to 1500 nm. ? 2011 Springer-Verlag.

    Title:Robust color correction in stereo vision
    Author(s):Wang, Qi(1); Yan, Pingkun(1); Yuan, Yuan(1); Li, Xuelong(1)
    Source: Proceedings - International Conference on Image Processing, ICIP  Volume:   Issue:   DOI: 10.1109/ICIP.2011.6116722  Published: 2011  
    Abstract:The phenomenon of color discrepancy between image pairs happens frequently in stereo vision systems. This inconsistence in color domain may cause difficulties when identifying point correspondence to reconstruct the scene depth. In this paper, we propose a robust algorithm to correct the color discrepancy between images. The proposed algorithm neither requires a color calibration chart/object which is a tedious procedure, nor explicitly compensates for the image as a whole, which possibly give bad correction results in local areas of an image. Instead, we correct the image region by region. Experiments show that the presented color correction algorithm is effective and efficient. ? 2011 IEEE.

    Title:Communication capacity of a free space laser communication system in atmospheric turbulent and disperse channels
    Author(s):Lu, Hongqiang(1,2); Zhao, Wei(1); Xie, Xiaoping(1,3)
    Source: Chinese Optics Letters  Volume: 9  Issue: SUPPL. 1  DOI: 10.3788/COL201109.S10603  Published: June 2011  
    Abstract:The pulse broadening and communication capacity in atmospheric turbulent and disperse channels are investigated. Models on pulse broadening are proposed, and the simulated results for a typical atmospheric condition and configuration are provided. The results show that the capacity of the system is affected mainly by atmospheric dispersion rather than atmospheric turbulence. The received pulse width can be minimized, and the system-achievable capacity can be maximized by selecting the optimum input pulse width. The proposed method can be used to predict the achievable capacity of a free space laser communication system in turbulent and disperse channels. ? 2011 Chinese Optics Letters.
