Development of an evanescent wave-based optical microfiber platform for label-free sensing applications

Despite the advantages of optical microfiber for sensing applications, its potential use of for real applications is often undervalued owing to its fragile characteristic that requires delicate handling and the bulky and costly optical setup. The work presented in this thesis aims to bridge this res...
