“…The experimental setup developed "in-house" [26] was implemented to fabricate FBG arrays during the fiber drawing process. The source of UV radiation was an Optosystems CL-5100 pulsed KrF excimer laser [29] with the 248 nm illumination wavelength and a pulse duration of 10 ns.…”

“…Thus, provided that the operating frequency range is within the reflection spectrum of the gratings, OFs with an FBG array are a good alternative to traditional Rayleigh fibers and, therefore, called "artificial Rayleigh fibers". In particular, they can be effectively used in such applications as coherent reflectometry [15,16] and random lasers [17][18][19][20][21][22][23][24][25][26].…”

“…The main advantage of random lasers with a cavity, based on an array of FBGs, is the narrow band emission with continuous-wave operation at relatively small cavity lengths (less than 10 m). However, previously such lasers' configurations have shown a relatively low efficiency of the laser's radiation (less than 10%) [20,21,26].…”

The Erbium “random” laser, based on the artificial Rayleigh fiber, has been comparatively studied in detail under two different pump conditions: 974.5 and 1485 nm pumping wavelengths. The artificial Rayleigh 7-m-long fiber was used as a laser cavity, it was formed by the ultraviolet (UV) inscription of the uniform array of the weakly reflective fiber Bragg grating (FBG) during the fiber drawing process. The UV photosensitivity of the Erbium-doped fiber originated from the specially developed (germanophosphosilicate) core glass composition. The emission spectrum of the fabricated “random” fiber laser had a single narrow peak at the 1548 nm wavelength. It was clearly revealed that the extension of the laser cavity by the separate wavelength-matched 90%-reflective FBG resulted in a significant laser efficiency growth. The highest laser slope efficiency of 33% and the laser output power of 80 mW were reached in the FBG-modified cavity at the 974.5-nm-wavelength pumping. The continuous-wave operation mode of this laser has been confirmed. The laser linewidth value measured by the delayed self-heterodyne technique was about 550 Hz.

Most distributed optical fiber sensors rely on commercially available telecom fibers, which are low-loss, inexpensive, and standardized. In the last few years, significant effort has been made to develop optical fibers optimized for specific sensing applications, with the view of improving the signalto-noise ratio (SNR) or extending the distance over which distributed optical fiber sensors (DOFS) operate. This tutorial reviews the efforts made by the scientific community towards the development of enhanced backscattering fibers and enhanced backreflection fibers, with a focus on DOFS.

“…Measurements with glass-fiber-based temperature devices are fairly common [ 4 , 5 , 6 ]. Solid microspherical resonators with whispering gallery modes (WGMs), which can be routinely manufactured by melting the tip of an optical fiber [ 3 ], form an important subclass of such systems.…”

In recent years, the use of optical methods for temperature measurements has been attracting increased attention. High-performance miniature sensors can be based on glass microspheres with whispering gallery modes (WGMs), as their resonant frequencies shift in response to the ambient parameter variations. In this work, we present a systematic comprehensive numerical analysis of temperature microsensors with a realistic design based on standard silica fibers, as well as commercially available special soft glass fibers (GeO2, tellurite, As2S3, and As2Se3). Possible experimental implementation and some practical recommendations are discussed in detail. We developed a realistic numerical model that takes into account the spectral and temperature dependence of basic glass characteristics in a wide parameter range. To the best of our knowledge, spherical temperature microsensors based on the majority of the considered glass fibers have been investigated for the first time. The highest sensitivity dλ/dT was obtained for the chalcogenide As2Se3 and As2S3 microspheres: for measurements at room temperature conditions at a wavelength of λ = 1.55 μm, it was as high as 57 pm/K and 36 pm/K, correspondingly, which is several times larger than for common silica glass (9.4 pm/K). Importantly, dλ/dT was almost independent of microresonator size, WGM polarization and structure; this is a practically crucial feature showing the robustness of the sensing devices of the proposed design.
