  • Low threshold 2 nd -order random lasing of a Fiber laser with a half-Opened cavity
    Optics express, 2012
    Co-Authors: Weili Zhang, Yunjiang Rao, Jun Mei Zhu, Zi Xin Yang Zi Nan Wang, Xin Hong Jia
    Abstract:

    In this paper, we reported the realization of 2nd-order random lasing in a half-Opened Fiber cavity, which is formed by a FBG with central wavelength at the 1st–order Raman Stokes wavelength and a single-mode Fiber (SMF) performing as a random distributed feedback mirror. Using this proposed method, the threshold of 1st-order (2nd-order) random lasing is reduced to 0.7 (2.0) W, which is nearly 2 times lower than that observed in a completely-Opened cavity.

  • A novel bio-detecting chip based on the Opened Fiber surface plasmon enhancement mechanism
    Fourth Asia Pacific Optical Sensors Conference, 2013
    Co-Authors: Guanjun Wang, Yiping Wang, Changrui Liao, Jiangtao Zhou
    Abstract:

    A novel bio-detecting chip configuration based on the Fiber surface plasmon enhancement mechanism is proposed and analyzed. Our improvement is proposing to couple the specialized shell-isolated gold nanoparticles into the sensing region of the Opened Fiber-integrated microfluidic chip, and achieving drastic surface plasmon enhancement by employing the guided optical mode. Simulation shows that the optical intensity distribution near the surface of exposed Fiber hole is enhanced drastically, which could be beneficial to the fluorescence or Raman enhancement. Our work could contribute to searching novel microfluidic chip based bio-detecting methods such as for tracing poisonous and harmful substances detection.

  • Design and Optimization of an Opened Suspended Core Fiber-Based SPR Sensor with Gold Cylinder Structures
    Applied Sciences, 2018
    Co-Authors: Wentan Jiao, Guanjun Wang, Jinrong Liu, Jing Zhang, Mengxing Huang
    Abstract:

    Abstract: In this study, an Opened three-hole suspended core Fiber surface plasmon resonance sensor structure based on the combination of photonic crystal Fiber and surface plasmon resonance (SPR) mechanism was proposed and analyzed. One hole in the clad layer was exposed to the outside, and a lay of gold cylinders with the same size and gap was placed along the inside of the Opened hole. The existence of the gold cylinders could stimulate the SPR effect and selecting the suitable gaps between the cylinders could enhance the SPR effect and increase its sensitivity. Then COMSOL software was used to simulate how the cylinder diameter, the gaps between the cylinders, and the fluid refractive index variation affect the sensor’s transmission loss spectrum, field enhancement effect, and the sensitivity. The optimized results show that the sensitivity of this proposed SPR sensor could be high, up to 1 × 10−5 RIU/nm, and it was much higher than the sensitivity of the existing photonic crystal Fiber SPR sensor (1 × 10−4 RIU/nm), which was an order of magnitude improvement. This study could provide a reliable theoretical basis for future research and design of real-time and high-sensitivity Opened Fiber SPR sensors.
