“…2, by increasing Raman pump power (RPP), the peak power of transmitted BP increases. In the range of RPP from 100 to 600 mW, the laser structure acts as single wavelength Brillouin fiber laser, in which the higher order Stokes line is not generated yet as reported in [18]. After reaching its power saturation, the first Brillouin Stokes line, which is back scattered in reverse direction by frequency shifted Brillouin scattering effect, is backscattered once more by Rayleigh and Brillouin effects.…”

We propose a simple Brillouin-Raman multichannel fiber laser with supportive Rayleigh scattering in a linear cavity without employing any feedback mirrors at the end of cavity. Brillouin and the consequences of Rayleigh scattering work as virtual mirrors. We employ a section of large effective area fiber in addition to a section of dispersion compensating fiber to enhance the optical signal-to-noise ratio of multi-channel Brillouin-Raman comb fiber laser. We able to produce a flat comb fiber laser with 37 nm bandwidth from 1539 to 1576 nm built-in 460 Stokes lines with 0.08 nm spacing. Furthermore, this Brillouin-Raman comb fiber laser has acceptable optical signal-to-noise ratio value of 16.8 dB for the entire bandwidth with excellent flatness and low discrepancies in power levels of about 2.3 dB between odd and even channels.

“…There are fifteen Stokes channels and fourteen anti Stokes channels that are generated, which are separated by 0.154 nm spacing to form a smooth triangle shape. This is better as compared to ten stokes channels and three anti stokes double spacing signals in previous work by using 6.7 km SMF [16], also 15 stokes and anti stokes lines with 0.16 nm spacing by using 10 km NZ DSP [19] or 5 stokes signals when they used shot length form PCF [20] or less in [21][22][23][24] by using Bi EDF as amplifica tion gain base on BFL.…”

A double frequency spaced multiwavelength Brillouin-Erbium doped fiber laser (BEDFL) with figure of eight cavity have been successfully developed and tested. Double frequency spacing is achieved by using a piece of 2 km of highly nonlinear fiber (HNLF) as a gain medium. Figure of eight configuration removes the odd order Stokes signals via a four port circulator. Fifteen Stokes channels are simultaneously generated with a spacing of 0.154 nm that is around 20 GHz, when the Brillouin pump and 980 nm pump powers are fixed at the optimized values of 6 dBm and 40 mW, respectively. Fourteen anti stoke channels are also obtained, which are generated through four wave mixing (FWM) process in the laser cavity. The output is smooth triangular comb. The BEFL can also be tuned from 1526.5 to 1567.5 nm.

“…Stimulated Brillouin scattering (SBS) based fiber laser is also a versatile mean to generate multi wave length laser due to its special specifications including simple configuration, narrow linewidth, and easy real ization of tuneable wavelength laser without using a comb filter [13,14]. Brillouin fiber laser (BFL) which is provided by this SBS approach utilizes nonlinear gain medium in optical systems.…”

Multi-wavelength Brillouin fiber laser generation using dual-pass approach

et al. 2012

View full text Add to dashboard Cite

A simple and compact multi wavelength tunable Brillouin fiber laser (BFL) in conjunction with dual pass approach is proposed and experimentally compared with the output of a conventional single ring cavity architecture. This BFL source is demonstrated using 10 km long non zero dispersion shifted fiber (NZ DSF) as a Brillouin gain medium. By single ring cavity configuration, odd order Brillouin Stokes lines appear in the backward direction with the line spacing 0.16 nm (~20 GHz) between each two consecutive waves. However, this single ring cavity in conjunction with dual pass configuration is able to generate Bril louin Stokes lines with 0.08 nm spacing by providing bi directional oscillations of Brillouin waves in both for ward and backward directions. With a Brillouin pump power of 15.3 dBm, approximately up to 17 Brillouin Stokes lines are generated which is tunable over 40 nm tuning range.
