Power budget analysis for waveguide enhanced Raman spectroscopy
Power budget analysis for waveguide enhanced Raman spectroscopy
Surface-enhanced Raman Spectroscopy (SERS) is a powerful tool for chemical analysis which can suffer from poor repeatability due to the sensitive nature of plasmonic interactions. Waveguide- enhanced Raman spectroscopy (WERS) is emerging as a competitive analytical tool which avoids nanostructured noble metal surfaces but which potentially provides comparable surface enhancements in a sensor format [1,2]. Comparison of these approaches suffers from ill-defined definitions of surface enhancement. We present a power budget analysis of WERS, relating the received power in a Raman emission line to the incident pump laser power, using waveguide surface intensity and Raman cross-section, allowing WERS optimisation and clear comparison of surface-enhanced techniques.

Abstract
Surface-enhanced Raman Spectroscopy (SERS) is a powerful tool for chemical analysis which can suffer from poor repeatability due to the sensitive nature of plasmonic interactions. Waveguide- enhanced Raman spectroscopy (WERS) is emerging as a competitive analytical tool which avoids nanostructured noble metal surfaces but which potentially provides comparable surface enhancements in a sensor format [1,2]. Comparison of these approaches suffers from ill-defined definitions of surface enhancement. We present a power budget analysis of WERS, relating the received power in a Raman emission line to the incident pump laser power, using waveguide surface intensity and Raman cross-section, allowing WERS optimisation and clear comparison of surface-enhanced techniques.
