X-ray Writing of Fiber Bragg Gratings (FBGs)
Abstract
Fabrication of nanoscale optical Fiber Bragg Gratings (FBGs) is one of the key manufacturing processes for fiber optics, which has many important applications in data communication and distributed remote sensing at a distance up to hundreds of kms. However, the fabrication of the FBGs is challenging. To meet such need, we propose a novel method to write the FBGs using high-flux synchrotron x-ray with a nanoscale gold/Si gratings to modulate the x-ray flux and thus change the refractive index contrast of the optical fiber to form the FBGs. The nanoscale gold/Si with high aspect ratio has been fabricated at the Center for Nanoscale Materials (CNM) at Argonne National Laboratory (ANL) and the preliminary experiment of x-ray writing of the optical fiber FBGs has been carried out at the Advanced Photon Source (APS) of ANL. The preliminary experiment shows promising result of the x-ray writing method of the optical fiber FBGs.
