Highly sensitive refractive index sensor based on adiabatically tapered microfiber long period gratings

Highly sensitive refractive index sensor based on adiabatically tapered microfiber long period gratings

We demonstrate a refractive index sensor based on long period grating (LPG) inscribed in a special photosensitive microfiber with double-clad profile. The fiber is tapered gradual enough to ensure the adiabaticity of the fiber taper. In other words, the resulting insertion loss is sufficient small....
