  • l band switchable dual Wavelength erbium doped fiber laser based on a multimode fiber bragg grating
    Optics Express, 2004
    Co-Authors: Xinhuan Feng, Shuzhong Yuan, Weigang Zhang, Xiaoyi Dong
    Abstract:

    In this letter, a simple, switchable dual-Wavelength erbium-doped fiber laser operating in L-band is successfully proposed and demonstrated. The two Wavelengths are specified by a Bragg grating formed in multimode fiber and the Wavelength separation is 1.7 nm. The multimode section including the multimode fiber grating selects not only the lasing Wavelengths but also the polarization states of the lasing lines. Stable dual-Wavelength operation can be achieved due to the spatial mode beating effect induced by a single-mode/multimode/single-mode fiber combination structure. By simple adjustment of a polarization controller, the proposed laser can operate in stable dual-Wavelength or switch between two Wavelengths, all at room temperature.

  • Novel four-Wavelength erbium-doped fiber laser as multichannel source in WDM system
    Rare-Earth-Doped Materials and Devices V, 2001
    Co-Authors: Lei Ding, Yanjun Xu, Shuzhong Yuan, Xiaoyi Dong, Chunliu Zhao, Chunfeng Ge
    Abstract:

    A novel four-Wavelength all-fiber laser based on fiber Bragg gratings is presented. The four Wavelengths are 1555.8, 1556.6, 1557.4 and 1558.s nm, respectively. Each output laser is 1 mW in power. The suppression ratio between adjacent Wavelengths is > 30 dB. The laser was applied in a Wavelength division multiplexing system and the 100 km transmission of 1.2 Gb/s nonreturn-to-zero code, 1.2 Gb/s return-to-zero, 2.5 GHz analogue signal and 5 GHz analogue signal was realized with it.
