“…In such fiber laser configurations, the change in the measurand is detected directly from the oscillation wavelength shift corresponding to the peak of the wavelength selection element used. However, changes in the measurands and environmental disturbances cause polarization variation, resulting in fluctuation of the oscillation wavelength, thereby causing a detection error [19,20,21].…”

In this study, we propose an Erbium-doped fiber (EDF) laser displacement sensor using bending characteristics of a cascadedchirped long-period fiber grating (C-CLPG), in which the C-CLPG assisted by a Faraday rotator mirror (FRM), namely double-pass C-CLPG, shows a channeled spectrum and plays both the roles of wavelength tunable filter and sensor element. In the sensing scheme, the spectral shift of the channeled spectrum due to the displacementinduced bending deformation is utilized. Due to the FRM reflection, the double-pass C-CLPG has characteristics suitable for sensing: the polarization-independent channeled spectrum and the compensation effect for polarization variation in the sensor section. In the experiment, it is successfully demonstrated that the EDF laser in a sigma-type cavity configuration (EDFσL) using the double-pass C-CLPG enables precise displacement measurement based on the oscillation wavelength shift corresponding to the spectral shift of the double-pass C-CLPG. Further, the advantage of this EDFσL is confirmed by comparison with the conventional EDF ring laser using the single-pass C-CLPG.

“…In recent years, multi-wavelength output lasers are often achieved with multi-wavelength filters. These filters usually consist of special structures to achieve interference effects, thus achieving multi-wavelength laser output, such as Michelson [9][10] , Mach-Zendel [11] , Fabry-Perot [12] , and Zagnac [13] interferometers. Mach-Zendel interferometer is one of the most used and widely used interferometers, and has been fabricated for gratings [14] , pull cones [15] , photonic crystal fibers [16] , multi-core fibers [17][18] , etc.…”

“…The maximum output wavelength number is 13, and the wavelength tuning by displacement- curvature can reach 2.3 nm mm −1 were observed under the condition of the OSNR values about 50 dB [10] . In 2022, Silva-Alvarado et al proposed a high stability wavelength switchable and tunable erbium-doped fiber laser by utilizing a Mach-Zehnder interferometer (MZI) to achieve single/dual emission operation by using the polarization controller to adjust the cavity losses [11] . In 2016, Gutierrez-Gutierrez et al proposed a multi-wavelength erbium-doped fiber laser and achieve wavelength switchable based on Fabry-Perot and Mach-Zehnder interferometers to obtain stable multiwavelength lasing lines with a wavelength separation of 0.86, 1.04, until 3.05 nm [12] .…”

A triple-wavelength erbium-doped fiber laser based on seven-core fiber (SCF) interferometer is proposed and successfully implemented. In the structure of the laser, a special structure of single-seven-single core is used to realize laser interference, which is composed of a 6 cm SCF and ordinary fiber optic patch cables fused by convex cone. In the laser with simple structure, triple-wavelength output with central wavelengths of 1530 nm, 1544 nm and 1558 nm are obtained by adjusting the polarization controller, and the optical signal-to-noise ratio (OSNR) of the triple-wavelengths is approximately 60 dB. The laser has high stability in terms of both wavelength and power. In the stability test of 150 min, the frequency drift of three wavelengths is approximately 0.4 nm, and the output wavelength peak power jitter is approximately 1.6 dB. The laser has the characteristics of simple structure and high stability, and has broad application prospects in the fields of optical fiber sensing, wavelength division multiplexing (WDM) optical communication system and microwave photonics.

“…Thus, complex data processing is not required, and relatively high speed, high S/N ratio, and high accuracy measurement are expected to be realized. However, such EDFRL configurations have the characteristics that the oscillation wavelength varies depending on the polarization state of the fiber in the cavity [19,20]; hence, due to birefringence variation caused by disturbances in the measuring environment, the oscillation wavelength fluctuates, which is a noise source that degrades the measurement precision.…”

In this work, we have constructed an Erbium-doped fiber sigma laser (EDFσL) using a double-pass cascaded-chirped long-period fiber grating (C-CLPG) from the viewpoint of the sensor applications. The double-pass C-CLPG is composed of a C-CLPG and a Faraday rotator mirror (FRM) and works as a comb-like wavelength selection element as well as a sensor section in the sigma-branch of the laser cavity. Further, due to the FRM reflection scheme, the double-pass C-CLPG compensates for birefringence variation in the sigma-branch during the sensing. In the experiment, the sensor section near the C-CLPG is intentionally deformed to induce birefringence variation assuming the external disturbances; nevertheless, it is confirmed that the double-pass C-CLPG provides stable polarization states. Then, under the birefringence variation, it is demonstrated that the proposed EDFσL can achieve a stable oscillation and resultant precise measurements in contrast to the simple EDF ring laser using the singlepass C-CLPG. In addition, for the demonstration of the sensor with external force to the fiber, the oscillation wavelength of EDFσL in response to axial strain is investigated, and a linear response with sensitivity ~0.32 pm/µε is obtained.
