Highly Sensitive Refractive Index Sensor Based on Adiabatically Tapered Microfiber Long Period Gratings
We demonstrate a refractive index sensor based on a long period grating (LPG) inscribed in a special photosensitive microfiber with double-clad profile. The fiber is tapered gradually enough to ensure the adiabaticity of the fiber taper. In other words, the resulting insertion loss is sufficiently s...
