High temperature microstructured fiber sensor based on a partial-reflection-enabled intrinsic Fabry–Perot interferometer
TLDR
A compact fiber Fabry-Perot interferometer (FPI) sensor for high temperature measurements is proposed and demonstrated, which shows a great potential for space-limited high temperature sensing applications.Abstract:
A compact fiber Fabry–Perot interferometer (FPI) sensor for high temperature measurements is proposed and demonstrated. The FPI consists of a small core microstructured fiber and single mode fiber, and it is enabled by partial Fresnel reflection at the interface of the two fibers and the end surface Fresnel reflection of the microstructured fiber. Simple splicing and cleaving techniques are used to construct such an interferometer, and the fringe contrast can reach 20 dB. Response to high temperature up to 1000°C is tested and a sensitivity of 17.7 pm/°C at 1570 nm is obtained. This proposed sensor is compact, and fabricated only with splicing and cleaving techniques, which shows a great potential for space-limited high temperature sensing applications.read more

Abstract: In this work we report experimental studies of an erbium-doped fiber laser design that simultaneously emits up to three wavelengths. The laser cavity configuration has an all-fiber, Fabry–Perot interferometer, based on the insertion of air cavities in the fiber, near one end of a conventional single-mode fiber. The laser emissions have a side-mode suppression ratio over 25 dB, wavelength variations around 0.04 nm, and 2 dB power fluctuations. By using a simple, controlled fiber curvature technique cavity losses are varied over a section of convectional single-mode fiber and the laser output is switched between single-, dual-, and triple-wavelength emission. Moreover, by applying a refractive index change over the fiber filter the emission wavelengths are shifted. The fiber laser offers a compact, simple, and low-cost design for a multiple wavelength outputs that can be adopted in future applications.

Micro Fabry-Perot interferometers in silica fibers machined by femtosecond laser.
TL;DR: Investigation of the strain and temperature characteristics of the two MFPIs with an identical cavity length show that the strain sensitivity of the PCF- based MFPI is smaller than that of the SMF-based M FPI due to their different waveguide structures, while the twoMFPIs have close temperature sensitivities due to the similar host materials.
