Abstract: We demonstrate a high-sensitivity directional magnetic field sensor based on a polarization-insensitive long-period fiber grating (LPFG). The LPFG is fabricated by hydrofluoric (HF) acid ...

By continuously adjusting the distance of the grating pair in the Yb-fiber oscillator, we measured the pump power fixed point frequency in different dispersion regimes and different intracavity ...

A polarization-grating is used to remold the object and the reference waves, and the fringe contrast of the generated hologram can be adjusted by changing the polarization of the illumination wave.
