“…При накачке на длине волны 2 µm ионы тербия практически не взаимодействуют с матрицей стекла. Отметим, что именно в световодах из стекол с Tb 3+ была впервые получена генерация лазерного излучения в среднем ИК диапазоне (на длинах волн 5.25 и 5.38 µm) [5,6]. У стекол с Dy 3+ имеются полосы поглощения в области слабого поглощения стекла.…”

“…Оптические волокна из ХС, легированных ионами РЗЭ, используются в разработках инфракрасных (ИК) лазеров и усилителей, а также широкополосных источников излучения [2,3]. В объемных образцах ХС, легированных ионами Tb 3+ , Pr 3+ и Ce 3+ [4], и в халькогенидных световодах, легированных Tb 3+ [5,6], продемонстрирована лазерная генерация в области длин волн 5−5.5 µm. На основе халькогенидного световода, легированного Pr 3+ , создан люминесцентный источник на длинах волн 4.0−5.5 µm, который прошел успешное тестирование в волоконнооптической сенсорной системе [7].…”

In the paper, results of measurements of the optical response of chalcogenide glasses of the Ga5Ge20Sb10Se65 composition doped with rare-earth ions Tb3+ or Dy3+, in the wavelength range of 0.7 – 1.5 μm by the method of IR spectroscopy are presented. Parameters characterizing the fundamental absorption band edge of the glasses - optical bandgap energy, Urbach tail parameter and weak absorption tail parameter - have been evaluated. It has been found that doping in low concentrations (up to 0.3 mass%) does not influence the optical bandgap energy and optical properties of the glasses in the range of the Urbach tail, but in the range of the weak absorption tail, optical response of the glasses depends on the activator concentration. Crystallization of the glasses produced by the direct melting method also depends on the activator concentration. In the glasses doped with Dy3+, absorption bands of the ion are located in the range of the weak absorption tail of the glass that makes possible energy transfer between the ions and the gap states of the charge carriers.

“…Various photonic devices based on these glasses offer enhanced performance compared to their silica-based counterparts; they are being actively studied in the frame of fiber, waveguide, and microresonator optics. Soft glasses usually have a much lower phonon energy and a wider transparency range than fused silica, thus allowing lasing in spectral regions that are unavailable for regular silica-based systems [ 11 , 12 , 13 , 14 , 15 , 16 ]. Chalcogenide and tellurite glasses exhibit enormous Kerr and Raman nonlinearities [ 17 , 18 ].…”

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.

“…To date, various types of fiber sensors based on evanescent wave have been proposed, among which chalcogenide fiber possess unique advantages for its wide transmission window which covers the mid-infrared molecular fingerprint. In recent years, researchers from University of Rennes 1 [ 1 , 2 , 3 ], Ningbo University [ 4 , 5 , 6 , 7 , 8 , 9 ], Zhejiang University [ 10 , 11 ], and other institutions [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ] have carried out extensive research on the mid-infrared evanescent wave absorption sensing technology, which proves that this technique can realize the real-time in situ qualitative and quantitative analysis of a variety of organic compounds. Dai et al developed a gas sensor based on a four-hole suspended core As 2 S 3 optical fiber, the sensitivity of which is less than 100 ppm for methane, and response time is estimated to be less than 20 s [ 8 ].…”

Evanescent wave absorption-based mid-infrared chalcogenide fiber sensors have prominent advantages in multicomponent liquid and gas detection. In this work, a new approach of tapered-fiber geometry optimization was proposed, and the evanescent efficiency was also theoretically calculated to evaluate sensing performance. The influence of fiber geometry (waist radius (Rw), taper length (Lt), waist deformation) on the mode distribution, light transmittance (T), evanescent proportion (TO) and evanescent efficiency (τ) is discussed. Remarkably, the calculated results show that the evanescent efficiency can be over 10% via optimizing the waist radius and taper length. Generally, a better sensing performance based on tapered fiber can be achieved if the proportion of the LP11-like mode becomes higher or Rw becomes smaller. Furthermore, the radius of the waist boundary (RL) was introduced to analyze the waist deformation. Mode proportion is almost unchanged as the RL increases, while τ is halved. In addition, the larger the micro taper is, the easier the taper process is. Herein, a longer waist can be obtained, resulting in larger sensing area which increases sensitivity greatly.
