Abstract
Optical fiber sensors for Raman spectroscopy based on hollow core optical fibers have shown great promise due to their low glass background, and high signal collection efficiency. We have previously demonstrated how glass billet extrusion can be used to make simplified hollow core fibers based on a single suspended ring. In this work we investigate the performance of these optical fibers as sensors for Raman spectroscopy. These fibers are used to excite samples at a range of laser excitation wavelengths to scan across the transmission profile of the optical fibers, allowing comparison of the performance of these fibers against commercially-available alternatives.
