Fiber and Integrated Optical Sensor Group is involved in studies related to optical mode interaction with the environment as well as among themselves. We have experties in developing photonic sensors and solutions for measuring minute changes in physical parameters, e.g. temperature, micro-strain, vibration, pressure, refractive-index of fluids. We also have experties in developing sensors and solutions for detecting various bio-chemical reagents, e.g. E. coli bacteria, microcystin-LR molecules, and cyanobacteria etc. in liquid phase. We possess IPs on a number of important discoveries and methods including two US patents on optical sensors and methods.
