“…Single frequency lasers with narrow linewidth have attracted research interest due to many potential applications in fiber optical communication systems and optical fiber sensing [1][2][3][4]. As well known, optical injection locking and selfinjection locking of DFB lasers has drawn attention especially for optical communication application as an efficient technique to improve the spectral and polarization performance of semiconductor lasers [5][6][7].…”

We study self-injection locking of DFB laser through ring fiber optic resonator in the different regimes. Experimentally measured transmitted and reflected from fiber cavity powers at undercoupled, critically coupled, and overcoupled regimes are properly coincide with the calculated values. Significant reduction of locked laser linewidth was observed. For the free running laser, the full-width at half-maximum linewidth was equal to 2.55 MHz assuming that line shape is Lorentzian. Meanwhile the self-injection locked DFB laser demonstrates linewidth equal to 2.5 KHz for undercoupled and critically coupled regimes and about two times more for overcoupled one.

“…Single longitudinal-mode (SLM) fiber lasers with narrow linewidth are of great research interest due to many potential applications in optical fiber sensing and fiber optical communication systems [10][11][12][13][14][15][16]. Various configurations of SLM lasers with linear and ring cavity have been reported.…”

“…Various configurations of SLM lasers with linear and ring cavity have been reported. Unidirectional ring laser configuration preventing spatial hole burning in the active fiber allows to get smaller linewidth as compared to lasers with linear cavities [11,12]. However, the operation of ring fiber lasers exhibits mode hopping and multimode oscillation [11].…”

Double-frequency Brillouin fiber lasers

Single longitudinal-mode Brillouin fiber lasers are very promising for many applications, such as coherent optical communication, interferometric sensing, coherent radar detection, and microwave photonics. In the lasers with doublyresonant cavities Stokes wave is generated by a short fiber ring cavities that are simultaneously resonant for pump and Stokes radiation. Therefore, such lasers emit coherent light in two laser lines separated by the Brillouin shift. We report a simple procedure allowing precise adjustment of the Brillouin fiber ring cavities for doubly-resonant operation and demonstrate two completely passive solutions enabling perfect stabilization of such cavities for generation of doublefrequency light. In our experiments, the first laser configuration is stabilized through self-injection locking mechanism implemented to the laser cavity with DFB semiconductor pump laser. Second configuration comprises a nonlinear fiber mirror based on the population inversion dynamical gratings induced in low-absorbed Er-doped fiber. The pump-toStokes conversion efficiency of ~40% in both cases and the Stokes linewidth of <500Hz for the first case and < 100Hz for the second are successfully demonstrated.

“…Multiple configurations of SLM lasers with linear and ring cavities have been reported. Potentially, a unidirectional ring laser configuration preventing spatial hole burning in the active fiber could allow one to get smaller linewidth as compared to lasers with linear cavities [2,3]. On the other hand, the operation of ring fiber lasers is still subject to multimode oscillation and mode hopping associated with comparatively long cavity length [2].…”

A single-longitudinal-mode Brillouin fiber laser passively stabilized at the pump resonance frequency with a dynamic population inversion grating

We demonstrate a single-longitudinal-mode Brillouin ring fiber laser passively stabilized at the resonance frequency with a 1.7 m section that is an unpumped polarization-maintaining erbium-doped fiber. The two coupled all-fiber Fabry–Perot interferometers that comprise the cavity, in combination with the dynamical population inversion gratings self-induced in the active fiber, provide adaptive pump-mode selection and Stokes wave generation at the same time. The laser is shown to emit a single-frequency Stokes wave with a linewidth narrower than 100 Hz.
