Hi sir,
Currently a team in our college (SRM Institute of Science and Technology) is working under guidance of Dr. R. kumar and Dr. S. Dhanalakshmi of ECE department on various applications of FBG and its variations. As a part of this we have to analyse the various design specifications to optimize the fiber so that we can go for fabrication. Our requirement till now is as listed below. We want to analyse which will suit our application. Can you help us? How can we use optigrating for such TFBG analysing?
