A fiber-taper-microsphere-coupled system was used to research the characteristics of laser oscillation and upconversion luminescence Yb3+:Er3+ co-doped phosphosilicate (YECP) microspheres. The YECP microspheres were fabricated by melting end filaments. Single- multimode at 1535-1565 nm within C-band obtained. In addition, output power single-mode 1545.5 can be as high 48.98 μW, which achieved under pump 9.63 mW, side-mode suppression ratio 51.49 dB. Upconversion fluorescence Er3+ 521, 532,...
What we believe to be a novel high-sensitivity fiber-optic pressure sensor based on the vernier effect and helical structure is proposed experimentally verified. The utilizes superposition of higher-order mode Mach-Zehnder interference Sagnac fundamental polarization in single fiber ring achieve effect. In addition, non-invasive encapsulation was fabricated convert rise fall value into change twist angle optical fiber. This approach reduces detecting medium signal while simultaneously...
We reported the observation of whispering gallery modes (WGMs) from silicon microspheres in C-band with a biconical tapered fiber-microsphere coupled system. experimentally studied resonant transmission spectra broadband light source and optical spectrum analyzer, measured X-ray diffraction pattern microspheres. analyzed WGMs microspheres, full-width at half-maximum was 0.12 nm, dip 3.5 dB (55% incident power). The Q factor microsphere 1.3×10 <sup...
A FMF-PMF-FMF sensor for measurement of the temperature and curvature based on Mach-Zehnder interferometer is proposed demonstrated experimentally. The length this fiber only 17mm. Through demodulating dip wavelength intensity transmitted spectrum, sensitivities to are 77 pm/°C - 5.02dB/ m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> , respectively. This simple easy fabricate, has high sensitivity, can be applied other fields, such...
