Long Period Gratings (LPG)-based sensors are widely used due to their higher sensitivity to various measurands. However, a single grating based LPG sensor system has the disadvantage of the probe being used in transmission mode due to the broad bandw...

The sensitivity of a Long Period Grating (LPG)-based refractive index (RI) sensor has been enhanced through an appropriate coating of a thin polymer layer, with a higher RI than that of the cladding, on the LPG. The performance of the coated sensor,... Read More about Refractive index sensor employing PVA-coated long period grating technology.
