Brillouin-like effects in rare-earth-doped bi-directional optical fiber amplifiers

“…Similar to SBS, the reported narrowband amplitude response is accompanied by a strong dispersive response, able to tailor the phase or group delay of a backward optical signal. In light of these effects, the Brillouin-like amplification could enrich the advanced Brillouin applications such as slow light [41][42][43][44] , stored light [45][46][47][48] , narrowband RF photonic filters [49][50][51] , optical processing [52][53][54] , distributed sensing [55][56][57][58][59][60] , narrowband spectrometers 61,62 , optical amplifiers 63 , narrow linewidth, spectrally pure RF sources 64,65 among others. The PIDG analog of the forward Brillouin scattering in optical fibers [66][67][68][69][70][71] could be of particular interest for further studies due to its enormous potential for practical applications in soliton fiber lasers as the method enabling the stabilization of harmonically mode-locked laser operation and super-mode noise reduction [72][73][74][75][76][77] .…”

All polarization maintaining Brillouin erbium-doped fiber laser with narrow linewidth and stable single longitudinal mode

“…[16] At present, there are three main types of Brillouin gain medium: single-mode fiber, nonlinear fiber and EDF. [17][18][19][20][21] As Brillouin gain medium, single-mode fiber has the characteristics of low price and stable excitation Brillouin effect. However, the length of single-mode fiber usually requires several kilometers, which lead to mode hopping due to the short longitudinal mode spacing in the cavity.…”

“…However, the length of single-mode fiber usually requires several kilometers, which lead to mode hopping due to the short longitudinal mode spacing in the cavity. [17,18] The other kind of Brillouin laser is nonlinear fiber as the gain medium. It only takes few meters to excite the SBS.…”

All Polarization Maintaining Brillouin Erbium-Doped Fiber Laser With Sub-kHz Linewidth Using Saturated Absorber and Self-Injection Feedback

“…In recent years, the Brillouin fiber laser based on the stimulated Brillouin scattering (SBS) has attracted significant interest [16]. At present, there are mainly three types of Brillouin gain medium fibers: the single-mode fiber [17], [18], the high nonlinear fiber [19] and the EDF [20], [21].

“…the gain medium, the single-mode fiber has the characteristics of low price and stable excitation SBS. However, the length of the single-mode fiber usually requires several kilometers, which lead to mode hopping operation due to the short mode spacing in the cavity [17], [18]. As a comparison, only a few meters of the high nonlinear fiber is requied to excite SBS, which can increase the mode spacing and reduce the phenomenon of the mode hopping.…”
