    Fabrication of long-period fiber gratings by CO2 laser in fiber under tension

    LIU Yun-qiTU Wen-taoYANG DanWANG Ting-yun...
    1-6页
    查看更多>>摘要：We demonstrate experimentally fabrication of CO2 laser written long-period fiber gratings (LPFGs) in single-mode fiber (SMF) under tension. New transmission dips can be generated due to the frozen-in stress in the fiber under tension.Dynamics analysis of laser writing process is performed to study the mechanism of the grating inscription. Experimental results show that the wavelength shift of new generated resonance dips can shift towards the longer or shorter wavelength with the increase of laser scanning cycles for gratings with different pitches.

    Error analysis for remote nonlinear iterative learning control system with wireless channel noise

    FANG YongYAN Hua-chao
    7-11页
    查看更多>>摘要：In this paper, the iterative learning control problem is considered for a class of remote control system over wireless network communication channel. The control performance of remote iterative learning control (R-ILC) system is analyzed and an error boundary of the stable output of the R-ILC system is obtained for the boundary stochastic noise channel. Finally,we obtain some rules to reduce the fluctuation caused by wireless channel noise through the analysis results for fluctuation boundary. The simulation results prove the proposed rule is correct.

    查看更多>>摘要：A novel scheme of optical modulation in 40 GHz radio-over fiber (RoF) system is proposed. It generates optical QPSK/16QAM signals in a serial-parallel structure of Mach-Zehnder modulators (MZMs). The millimeter-wave is obtained with optical frequency multiplication (OFM). Furthermore, modulation on optical-wave is transferred onto millimeter-wave.It can be used to increase transmission capacity of millimeter-wave RoF systems.

    Interference cancellation scheme for uplink cognitive radio systems

    WU ZhuoYAN Li-jia
    16-20页
    查看更多>>摘要：This paper investigates the interference cancellation (IC) scheme for uplink cognitive radio systems, using the spectrum underlay strategy where the primary users (PUs) and the secondary users (SUs) coexist and operate in the same spectrum. Joint MMSE-based parallel interference cancellation (PIC) and Turbo decoding scheme is proposed to reduce the interference to the PUs, as well as to the SUs, in which the minimum mean square estimation (MMSE) filter is only employed in the first iteration, regarded as the "weakest link" of the whole detection process, to improve the quality of the preliminary detections results before they are fed to the Turbo decoder. Simulation results show that the proposed scheme can efficiently eliminate the interference to the PUs, as well as to the SUs.

    Source localization with minimum variance distortionless response for spherical microphone arrays

    HUANG Qing-huaZHONG QiangZHUANG Qi-lei
    21-25页
    查看更多>>摘要：To improve localization accuracy, the spherical microphone arrays are used to capture high-order wavefield information. For the far field sound sources, the array signal model is constructed based on plane wave decomposition. The spatial spectrum function is calculated by minimum variance distortionless response (MVDR) to scan the three-dimensional space. The peak values of the spectrum function correspond to the directions of multiple sound sources. A diagonal loading method is adopted to solve the ill-conditioned cross spectrum matrix of the received signals. The loading level depends on the alleviation of the ill-condition of the matrix and the accuracy of the inverse calculation. Compared with plane wave decomposition method, our proposed localization algorithm can acquire high spatial resolution and better estimation for multiple sound source directions, especially in low signal to noise ratio (SNR).

    Surface-enhanced Raman scattering sensor based on fused biconical taper zone of optical fiber

    CHEN Zhen-yiBAI HuaZHANG KunCHEN Na...
    26-30页
    查看更多>>摘要：In this paper, a novel surface-enhanced Raman scattering (SERS) sensor combined with fused biconical taper fiber (FBTF) and film coated with silver sols is proposed. This structure is designed to significantly increase the SERS active surface when the length of the taper is increased and the radius is reduced, since the penetration depth is inversely proportional to the taper radius and proportional to the taper length according to the fiber-optic evanescent-wave theory. Based on the SERS sensing principle, the feasibility of FBTF sensor is analyzed in this paper. As a result, the Raman spectrum of R6G is obtained from the fused biconical taper zone surface coating with the silver sols in our experiments. The detected concentration is up to 10-7 mol/L.

    Flat-top and low-dispersion optical interleavers based on nested prism pair structure

    ZHANG Juan
    31-34页
    查看更多>>摘要：A novel flat-top and low-dispersion optical interleaver using ring cavities (RCs) in a Mach-Zehnder interferometer (MZI) is proposed. It is composed of eight mirrors and two nested prism pairs. Each prism and the two mirrors behave as a RC. Phase shift of RC is a periodic function of the frequency of the input light which acts as a phase dispersive mirror. The two phase shifts needed to achieve a flat-top spectral passband are provided by Fresnel reflectivities at the prism-air interface of the two RCs. The optimum interface reflectivities for flat passband, high isolation and low dispersion can be obtained only by choosing an appropriate material for the prism in each RC. The proposed interleaver in a 25 GHz channel spacing application exhibits a 0.5 dB passband greater than 24 GHz (96% of the spacing), a 30 dB stopband greater than 21.2 GHz (84.8% of the spacing), a channel isolation higher than 32 dB and chromatic dispersion ±50 ps/nm within the range of center-frequency ±2 GHz ITU passband.

    Transmission properties of fractal Cantor distribution with left-handed materials

    XIAO Zhong-yinWANG Zi-hua
    35-37页
    查看更多>>摘要：Transmission properties of fractal Cantor distribution with left-handed materials (LHM) are investigated. The transmittance and reflectance spectra can be calculated by using the optical transmission matrix method. Comparing with the conventional Cantor multilayers, these structures with LHM have double functions of stopbands and defects. Through adjusting the thickness of dielectric layers, the properties of stopbands and defects can be obtained, respectively. For stopbands, a broad stopband filter is studied. For defect modes, multi-frequencies narrow passband filters are proposed.

    Area-time associated test cost model for SoC and lower bound of test time

    ZHANG Jin-yiWENG Han-yiHUANG Xu-huiCAI Wan-lin...
    43-48页
    查看更多>>摘要：A novel test access mechanism (TAM) architecture with multi test-channel (TC) based on IEEE Standard 1500 is proposed instead of the traditional sub-TAM structure. The cost model of an area-time associated test and the corresponding lower bound of system-on-chip (SoC) test time are established based on this TAM architecture. The model provides a more reliable method to control the SoC scheduling and reduces the complexity in related algorithm research. The result based on the area time associated test cost model has been validated using the ITC'02 test benchmark.
