“…Kang et al [ 40 ] also noticed that reducing the cross-sensitivity between the measurands is a major problem in strain sensing. Different from the above two researchers, Kang found that little effort was made to describe the possibility of simultaneous measurement based on FRL sensors, and presented a novel laser sensing configuration for both strain and temperature in 2015.…”

A review for optical fiber sensors based on fiber ring laser (FRL) demodulation technology is presented. The review focuses on the principles, main structures, and the sensing performances of different kinds of optical fiber sensors based on FRLs. First of all, the theory background of the sensors has been discussed. Secondly, four different types of sensors are described and compared, which includes Mach–Zehnder interferometer (MZI) typed sensors, Fabry–Perot interferometer (FPI) typed sensors, Sagnac typed sensors, and fiber Bragg grating (FBG) typed sensors. Typical studies and main properties of each type of sensors are presented. Thirdly, a comparison of different types of sensors are made. Finally, the existing problems and future research directions are pointed out and analyzed.

“…Several techniques such as hybrid FBG/long-period grating (LPG) [14], different diameter FBG's [15], FBG in polymer optical fiber [16], FBGs written in fibers with different levels of doping elements [17] FBGs written in single mode fiber (SMF) and twin core fiber (TCF) [18], four-core fiber combined with a FBG [19], a combination of Fabry-Perot interferometer (FPI) and FBG [20], superstructure FBG [21], coated FBG [22], FBG in Polarization Maintaining Fiber (PMF) [23], π-Phase-Shifted FBG [24], chirped FBG [25], and FBG written in PANDA fiber [26] have been proposed to solve the problem. All works are also in the goal of minimizing the complexities as well as costs of structures of the sensors [27][28].…”

Many efforts have been devoted to simultaneous measurements of strain and temperature by FBG sensors and several improving techniques have been resulted and implemented on the measurement. Most of them are based on two or more FBGs configurations or a single non-uniform FBG implementation. We propose simultaneous measurement of temperature and strain based on peak power changes and Bragg wavelength shifts using only one uniform fiber Bragg grating (FBG). We placed a ramp with the angle of θ, similar to a tilted cantilever beam, on an assumptive structure and stuck a uniform FBG on it. When a uniform strain applied to a structure, the cantilever beam converts it to a non-uniform strain distribution along with itself and consequently the uniform FBG. By creating this non-uniform strain distribution, the peak power of the reflection spectrum of the FBG will be sensitive to strain changes. In addition, the Bragg wavelength shift will be sensitive to both temperature and strain parameters. According to our simulation, temperature sensitivity of 14.15 pm/℃ is obtained for FBG sensor without any changes in the peak power. The strain sensitivity of 0.7837 pm/με, and a nonlinear sensitivity according to a quadratic function for peak power variation are also observed.

“…Due to the flexible structure, large mode field area (Knight et al, 1998), photonic crystal fibers maintain the superior characteristics of infinite single mode (Birks et al, 1997), low loss and adjustable dispersion (Ferrando et al, 2000;Ortigosa-Blanch et al, 2000;Zhang, 2012), overcoming the defects of conventional fibers, and have replaced the traditional YAG. So far, photonic crystal fibers have great potential for applications in fiber lasers, fiber optic communication (Han, 2010), fiber optic sensing (Kang et al, 2015) and nonlinear optics (Dudley and Taylor, 2009), so researchers have extensively studied the doping of different ions in photonic crystal fibers, and thus prepared photonic crystal fiber lasers with different output characteristics.…”

Compared with conventional solid-state lasers, fiber lasers have the advantages of small size, simple cooling system, and good output beam quality, enabling them an extended service lifetime in industrialized environments. Periodically arranged photonic crystals have been the most important gain medium for high-power laser applications, which overcame the problems in fiber lasers such as small mode field, low degree of nonlinearity, and non-adjustable dispersion. In this mini-review, we summarize the recent advances of typical ion-doped photonic crystal fiber lasers doped, discuss the challenges, and provide an outlook on the future developments in ion-doped photonic crystal fiber lasers.
