Accurate intrusion recognition along the optical fiber is still an enormous challenge in the distributed acoustic sensing (DAS) based security system. Especially in the complex environments, variou…
We proposed a silver-coated 45° radiated tilted fiber grating (45° RTFG) based interferometer, in which the 45° RTFG is working as a beam splitter and a coupler, and the light transmitting in th…
In this article, we have theoretically and experimentally investigated the unique vector refractive index (RI) sensing property of tilted fiber grating (TFG). Due to the orthogonal symmetric gratin…
Recent discovery on scalar-vector features of ultrashort pulses sheds new light on the polarization dynamics of ultrafast fibre lasers. Here, we report on the generation of scalar and vector solito…
