Abstract
A method of fabricating Fiber Bragg gratings in a micro/nanofiber using ultrashort pulse irradiation, the method includes elongating and flame-brushing a single mode optical fiber to create a micro/nanofiber, and generating the ultrashort pulse irradiation to induce a plurality of refractive index changes at predetermined intervals within the micro/nanofiber, wherein the ultrashort pulse propagates through a focusing element and a diffractive element prior to propagating on the micro/nanofiber.
