Acoustic wave coupling in dual-wavelength orthogonal polarized Brillouin random fiber laser (BRFL) based on polarization-maintaining (PM) fiber is characterized experimentally for the first time. D…
Strain sensor with low temperature crosstalk over large strain range is essential for field monitoring of structural safety. We develop a tension-compression strain sensor with high strain sensitiv…
A novel theoretical calculation method is proposed to obtain Brillouin power and frequency coefficients for strain and temperature of optical fibers used in Brillouin optical time domain sensors. F…
By using the plane-by-plane grating inscription method with an fs-IR laser, random fiber gratings with low laser-induced loss were fabricated in SMF-28 fiber for distributed temperature sensing. Co…
