Optical Fibre Sensors This research theme is devoted to the creation and fabrication of chemical sensors based on a range of sensing platforms modified with advanced functional nano-materials for applications in fields ranging from healthcare [1] and environmental monitoring [2] to food and beverage quality assessment [3]. Group is working on the development of the optical fibre sensors based on the long period gratings (LPGs) [4-10], fibre Bragg gratings (FBGs) [11], tapered optical fibres [12], evanescent wave spectroscopy [13] and refection optrodes [1] The principle of operation of the optical fibre sensors based on various platforms is explained in Figure 1.
