  • Multi-Channel Broadband Brillouin Slow Light With Multiple Longitudinal Mode Pump
    Journal of Lightwave Technology, 2012
    Co-Authors: Xuping Zhang, Rugang Wang, Yuejiang Song, Amarendra K. Sarma
    Abstract:

    Independent delay control of multi-channel signals based on stimulated Brillouin scattering slow light is proposed and demonstrated for the first time by using a Multiple Longitudinal Mode fiber laser. Two independent broadband Brillouin pumps are generated by a fiber ring laser, which use a semiconductor optical amplifier as gain medium. The spectrum of each pump is comprised of a large number of Longitudinal lasing Modes, separated by 7 MHz and spanning a bandwidth of 11.6 and 11.2 GHz, respectively. The multi-channel broadband Brillouin slow light is demonstrated by using 8 Gb/s data signals. The signals in both channels are continuously delayed by as much as 80 ps at 21 dBm pump power, and the maximal delay-time with error free operation (bit error rate

  • Broadband Brillouin slow light with Multiple-Longitudinal-Mode, tunable pump
    Chinese Optics Letters, 2012
    Co-Authors: Rugang Wang, Yuejiang Song, Xuping Zhang
    Abstract:

    We propose and demonstrate broadband Brillouin slow light using a Multiple-Longitudinal-Mode tunable fiber laser as Brillouin pump. A tunable broadband Brillouin pump with a tuning range from 1 520 to 1 555 nm is generated using a fiber ring laser with a semiconductor optical amplifier (SOA) as its gain medium. The pump spectrum consists of a large number of Longitudinal Modes separated by 6 MHz. The 3-dB bandwidth is about 11.5 GHz, and its fluctuation is less than 100 MHz within the tuning range. An 8-Gb/s data signal can be delayed by up to 83.0 ps (bit error rate < 10?9) at 17-dBm pump power.

  • Tunable bistability in hybrid Brillouin–erbium single-frequency fiber laser with saturable absorber
    Journal of the Optical Society of America B, 2016
    Co-Authors: Tantan Wang, Minglei Qin, Liang Zhang, Cheng Feng, Li Zhan
    Abstract:

    We demonstrate optical bistability with flexible tunability based on a single-frequency hybrid Brillouin–erbium fiber laser with a saturable absorber. An unpumped erbium-doped fiber is used as the saturable absorber to play the role of a dynamic ultranarrow self-tracking filter and suppress the Multiple-Longitudinal-Mode operation. By properly adjusting the power of two pumps (980 nm pump and Brillouin pump), the bistable region can be conveniently tuned from 23 mW to ∼1  W. The smallest bistable region (23 mW) appears under a fixed Brillouin pump power (1.104 W). The result shows that the proposed fiber laser performs a single-Longitudinal-Mode status with excellent stability of the output wavelength and optical power.

  • Dynamics and limitations of superluminal propagation based on long-cavity Brillouin fiber lasing oscillation
    Journal of the Optical Society of America B, 2016
    Co-Authors: Minglei Qin, Liang Zhang, Tantan Wang, Li Zhan
    Abstract:

    The mechanism of superluminal propagation in a long-cavity Brillouin fiber laser system was theoretically analyzed and experimentally evaluated. Considering the impact of the pump power spectral density and the modulation frequency, the formulation of the fractional advancement was deduced. The limitation factors for superluminal propagation, such as the cavity length, gain coefficient, and effective Mode field area, were also studied in detail. Consequently, the simulations and experiments indicate that the Multiple-Longitudinal-Mode operation is the main limitation to the distance of superluminal propagation based on Brillouin lasing oscillation. Besides, the fractional advancement of light pulses with different modulation frequencies or depths was thoroughly investigated to optimize advancement efficiency. This research could serve as the theoretical underpinning for long-distance superluminal propagation.

    Recent progresses towards distance-limitless superluminal propagation based on stimulated Brillouin scattering have been presented. By suppressing Multiple-Longitudinal-Mode lasing oscillation, Brillouin-induced superluminal propagation through hundreds-of-meter optical fibers can be successfully achieved.
