13 μm fiber grating in a thin-core fiber for LP01–LP11 mode converters and sensing ability

We demonstrate an all-fiber structure that can realize LP01 − LP11 mode conversion and twist measurement. It is a thin-core fiber (TCF) grating at a wavelength of 1310 nm cascaded to a short segment of a TCF of a different core size. It is found that the different core size of the TCF between the fi...
