“…For example, the substance could be infiltrated as a gas at high pressure along the fiber heated at a high temperature, while condensing at the (lower) operating temperature. The proposed approach paves the way for many potential sensing applications, such as distributed electrical field sensing by liquid crystal infiltration 41 , magnetic field sensing using magnetic fluid infiltration 20 , 42 , or enhanced Brillouin sensing using highly nonlinear liquid infiltration 43 . The SBS could be even excited into the liquid through the evanescent field of the guided mode 26 : due to the much lower acoustic velocity in the liquid, the BFS of the liquid would be well separated by the BFS of silica.…”

“…A suspended-core fiber (SCF) with a 3-µm pure silica core is used for experiments. The design of this fiber ensures a high overlap of the guided mode with the air holes running along its length, making it particularly efficient as a sensing platform 20 – 22 . We show, both numerically and experimentally, that filling the holes of a SCF with a liquid having a specific refractive index, the temperature sensing coefficient can be reduced, while keeping the strain sensing coefficient almost unchanged.…”

We demonstrate the possibility to modify the Brillouin scattering properties of a microstructured pure-silica core optical fiber, by infiltrating a liquid inside its holes. In particular, we show that the dependence of the Brillouin frequency shift (BFS) on the temperature can be reduced by infiltration, owing to the large negative thermo-optic coefficient of the liquid. Infiltrating a chloroform-acetonitrile mixture with a refractive index of 1.365 inside the holes of a suspended-core fiber with a core diameter of 3 µm, the BFS temperature sensing coefficient is reduced by ≈ 21%, while the strain sensitivity remains almost unaltered. Besides tuning the temperature sensing coefficient, the proposed platform could find other applications in Brillouin sensing, such as distributed electrical and magnetic measurements, or enhanced Brillouin gain in fibers infiltrated with high nonlinear optical media.

We propose a kind of surface plasmon polaritons (SPPs)-assisted dual-V-type four-level composite system used for high-sensitivity weak magnetic field measurement. The SPPs are excited by a D-shaped photonic crystal fiber (PCF) deposited with gold nanowires, and are interacted with the above quantum emitter from the rubidium atomic vapor. In the presence of the external magnetic field, Faraday rotation symmetry is broken due to Zeeman effect, resulting in the polarization plane rotation when a linearly polarized probe field goes through the above quantum emitter. With the help of the coupled field and SPPs, Faraday magneto-optical rotation (MOR) are effectively regulated. The Rabi frequency of the coupled field (Ω c ), quantum interference degree (q), and phase difference (φ) between the applied fields show strong dependence on the MOR angle and magnetic field measurement sensitivity. The simulated results reveal that the maximum MOR angle and magnetic field sensitivity both damp with Ω c expanding and q reducing. The maximum dichroism-independent MOR angle of 89.97° is realized for φ = 0° (180°), and the magnetic field sensitivity of 10.88°/Oe is obtained in the sweeping range of −8.88–8.88 Oe for q = 0.99, being 2.66°/Oe higher than that in the absence of SPPs (q = 0). Most importantly, the output probe field with different polarization forms can be realized by adjusting the φ value. Hence, the proposed device exhibits the potential in the fields of weak magnetic field measurement and polarization control.
