Dash J.N.Jha R.2025-02-172014https://idr.iitbbs.ac.in/handle/2008/515We experimentally demonstrate a PCF based modal interferometer with macrobending. FEM is used to generate the modes in bent PCF. The interferometer shows a sensitivity of 270 nm/RIU for a bend radius of 2.43 cm. � OSA 2014.enConference Paper
