Sensitivity Comparison of Free-Space and Waveguide Raman for Bulk Sensing

Jérôme Michon, Derek Kita, and Juejun Hu

Not Accessible

Your library or personal account may give you access

Abstract

We compare the bulk sensing performance of waveguide-enhanced Raman spectroscopy (WERS) sensors and generic free-space Raman systems using ray tracing. We show that WERS sensors can yield a better signal-to-noise ratio.
