Abstract: A novel fiber inline Mach-Zehnder interferometer (MZI) is proposed for simultaneous measurement of curvature and temperature. The sensor composes of single mode-multimode-dispersion compensation-multimode-single mode fiber (MMF-DCF-MMF) structure, using the direct fusion technology. The experimental results… read more here.

DOI: 10.1016/j.optlastec.2020.106442
Abstract: Abstract A dual-frequency optoelectronic oscillator (OEO) incorporating cascaded fiber-Bragg-grating Fabry–Perot (FBG-FP) cavities designed for both curvature and temperature sensing is proposed and experimentally validated. The OEO is composed of two tunable laser diodes (TLDs), a… read more here.
