“…The most possible way is to shorten the cavity length of a BEFL. Special fibers with high-nonlinearity, such as Bismuth-based EDF and photonics crystal fiber, have been reported to shorten the length of the Brillouin gain medium [15], [16]. However, these BEFLs require high pump threshold ( ) due to the serious attenuations of the special fibers, and the laser output power is also limited by the resonator losses.…”

“…With sufficient 980 nm pump power, the total gains of the Brillouin Stokes overcome the losses in the cavity and clockwise-direction Brillouin Stokes oscillation is generated in the loop finally. Unlike the previous compact BEFL in [15], our BEFL adopts a narrow-band TOF which is a key element of our laser. There are two reasons to adopt a TOF.…”

In this paper, we derive a numerical model to analyze the compact Brillouin/erbium fiber laser with a short commercialized normal erbium-doped fiber (EDF) as both the Brillouin and linear gain media. The effects of the 980 nm pump power, the Brillouin pump power, the EDF length, and the output coupling ratio on the BEFL output power characteristics are simulated. The theoretical results predict that a short commercialized normal EDF is capable for a high-power low-threshold compact BEFL. Based on the theoretical analyses, a BEFL using only 4 m normal EDF as the gain medium is designed and constructed. The measured results demonstrate that this BEFL presents low pump threshold ( ), high output power ( ), single-mode operation and low relative intensity noise ( ). This BEFL shows potential applications in distributed Brillouin fiber sensors, interferometric fiber sensors, and coherent optical communications, etc.Index Terms-Brillouin/erbium fiber laser, Erbium-doped fiber, single-mode fiber laser, stimulated Brillouin scattering.

“…In these systems, the shortest-wavelength channel is most depleted as it can pump many channels simultaneously as long as the wavelength difference is within the bandwidth of the Raman gain [22]. Recently, among all non-silica fibers with large nonlinearities, fibers based on bismuth oxide (Bi 2 O 3 ) have attracted considerable attention in recent years for applications related to nonlinear fiber optics [23][24][25][26][27].…”

Abstract.A multiple wavelength laser source is generated by a Brillouin seed signal and a compacted hybrid Raman / bismuth-based erbium doped fiber amplifier (Bi-EDFA) in a linear cavity. The gain media of the Raman/Bi-EDFA is only a 2.15 m Bi-EDF pumped bi-directionally by two laser diodes (LDs). In comparison to all of the conventional multiple wavelength sources generated via using the same Bi-EDF and LDs, the proposed multiple wavelength source has much more number of lines due to using Raman and EDF amplification.

“…Multi-wavelength fiber lasers are of great interest for their potential applications in wavelength-divisionmultiplexed (WDM) communication systems, fiber sensors and optical instrumentations [1][2][3]. Both the erbium-doped fiber amplifier (EDFA) and the semiconductor optical amplifier (SOA) are excellent candidates for the gain medium of the lasers [4,5].…”

A multi-wavelength laser source is demonstrated with a semiconductor optical amplifier (SOA) as a gain medium. A multi-wavelength comb with equal spacing is achieved due to Fabry-Pe´rot modes of the SOA which oscillates in the ring cavity. A 100 m long photonics crystal fiber (PCF) is inserted in the ring cavity to provide a nonlinear gain by four-wave mixing (FWM) so that the output comb spectrum can be greatly broadened and flattened. The stability of the ring laser is also increased due to the efficient FWM phenomenon occurring in the PCF. The SOAbased laser can generate 35 lasing lines with equal spacing of 0.28 nm and extinction ratios of more than 30 dB at room temperature. The number of channels of the multi-wavelength laser can be controlled flexibly by changing the ratio of the coupler used in the ring cavity configuration as well as controlling the polarization state of the oscillating laser.
