Linewidth narrowing and stabilization of semiconductor laser light generation is of great research interest governed by the huge demand of compact cost-effective narrow-band laser sources for many potential applications. In 2012 we have demonstrated a simple kHz-linewidth laser just splicing a standard distributed feedback (DFB) laser diode and a few passive telecommunication components. The principle of operation employs the mechanism of self-injection locking that significantly improves DFB laser performance. While a typical linewidth of free-running DFB semiconductor lasers ranges from a few to tens MHz, self-injection locking of a DFB laser through an external fiber ring cavity causes a drastic reduction of its laser linewidth down to a few kHz. The advantage of the proposed configuration is that the same external fiber ring cavity could be used for self-injection locking of a DFB laser and as Brillouin scattering media to generate Stokes shifted optical wave. However, a continuous laser operation at two frequencies has not been reported yet preventing it from many prosperous photonic applications. Here, we introduce a simple dual-frequency laser configuration. In our approach, the implementation of self-injection locking into the Brillouin ring fiber laser helps to maintain coupling between the DFB laser and an external high-Q fiber cavity enabling dual-frequency laser operation. Specifically, the same ring fiber cavity is used to generate narrow-band light at the pump frequency (through self-injection locking mechanism) and narrow-band laser light at Stokes frequency (through stimulated Brillouin scattering). The system is supplied by a low-bandwidth active optoelectronic feedback circuit controlled by a low-cost USB-DAQ card that helps the laser to maintain the desired operation mode. The fiber configuration reduces the natural Lorentzian linewidth of light emitted by the laser at pump and Stokes frequencies down to 270 Hz and 220 Hz, respectively, and features a stable 300-Hz-width RF spectrum recorded with the beating of two laser outputs. We have explored key features of the laser performance, revealing its stability and applicability to RF harmonic generation of high spectral purity as an additional benefit of the proposed technique.

Self-injection locking - an efficient method to improve the spectral performance of semiconductor lasers without active stabilization - has already demonstrated its high potential for operation with single-longitude-mode fiber lasers. Recently, we demonstrated that self-injection locking of a conventional DFB laser through an external fiber optic ring cavity causes a drastic decrease of the laser linewidth and makes possible its direct application in a phase-sensitive optical time domain reflectometry (φ-OTDR) acoustic sensor system. Detection and localization of dynamic perturbations in the optical fiber were successfully demonstrated at the distance of 9270 m. However, the ability of the system to restore the perturbating frequency spectrum was not quantified. Here, we have evaluated the performance of a φ-OTDR system for acoustic/vibration measurements utilizing a conventional telecom DFB laser self-stabilized through an external PM optical fiber ring resonator. The use of PM fiber components prevents the polarization mode-hopping that is proved to be a major source of the laser instability, resulting in single frequency laser operation with 6 kHz linewidth. The laser diode current and the laser fiber configuration temperature both have been stabilized with accuracies better than 0.3%. All laser components have been placed into a special insulating box to protect the laser from external perturbations. Under these conditions, the typical duration of laser operation in self-maintaining stabilization regime is ~30 minutes. The laser long-term frequency drift is estimated to be less than ~30 MHz/min. This low-cost solution is directly compared with the use of a commercial, ultra-narrow linewidth (~ 100 Hz) fiber laser implemented into the same setup. Both systems are tested for measurement of the frequency of vibration applied to a fiber at a distance of 3500 m. The obtained SNR value higher than 6 dB demonstrates the ability of the DFB laser to be used in distributed measurements of vibrations with frequencies up to 5600 Hz with a spatial resolution of 10 meters.

Self-injection locking, an efficient method to improve the spectral performance of semiconductor lasers without active stabilization, has already demonstrated its high potential for operation with single-longitude-mode fiber lasers. Recently, we have demonstrated significant line-narrowing (more than 1000 times) of the conventional low-cost DFB laser locked to an external fiber optic ring resonator. However, dynamical behavior of such a laser exhibits mode-hopping making its applications for distributed acoustic sensing rather questionable. In order to explore capacity of the injection locked laser for a phase-OTDR, we have designed a simple configuration of the injection locking DFB laser and applied it for detection and localization of perturbations with a phase-OTDR based distributed vibration sensor. The conventional DFB laser locked at critical coupling regime through fiber optic ring resonator of 3.75 m length (Free Spectral Range is 54.5 MHz) delivers CW mode-hoping free radiation with a linewidth of about ~5.0 kHz, i.e. ~200 times narrower than the linewidth of free-running laser. In combination with the moving differential processing algorithm such a laser is capable to provide high SNR distributed measurements of vibrations and dynamic strain perturbations. The fiber under test comprises three sections of standard single mode fiber, with a total length of ~4.5 km. Perturbations have been locally implemented into the test fiber at two positions using a shaker and a piezoelectric stretcher, respectively. In the first case, perturbations of the fiber induced by the shaker at a frequency of 815 Hz have been recognized as a peak in the recorded and processed traces with a signalto- noise ratio (SNR) of 12 dB over a 10 m resolution cell. In the second case, dynamical strain induced by the fiber stretcher over 40 m at a frequency of 3 kHz is shown in a similar pronounced peak with a signal-to-noise ratio (SNR) of 11 dB. These signatures are similar to the results obtained with a commercial 1 kHz linewidth laser employed with the same phase- OTDR setup. We believe that proposed solution could be a basis for development of a cost-effective phase-sensitive OTDR for distributed sensing specified for the distance up to tens of kilometers.
