| Summary: | Nowadays, optical fiber sensors have been frequently used in place of electrical sensors due to their many advantages such as sensitivity, low cost, immunity to electromagnetic interference, etc. Amongst the most common type of fiber sensors developed are grating based sensor as they easy to manufacture and has multiplexing capability. In this project, we have chosen to use a tapered microfiber long-period grating (TMLPG) to sense refractive index change of the ambient fluid as LPG is known to couple light from the core to the cladding and hence sensitive to the refractive index change of the surrounding medium.
