Lithographically patterned fiber bundles for in-vivo Raman spectroscopy

Abstract

Raman spectroscopy is used extensively, from handheld substance identification systems to in-vivo cancer detection. The ability to quickly and non-invasively identify compounds based on intrinsic vibrational signatures has seen Raman applications skyrocket in recent years - many using endoscopic probes. This paper describes the modeling, deposition, lithographic patterning, and testing of filters directly deposited onto the distal tip of a fiber bundle. These spectrally sharp bandpass and long pass filters allow for the detection of Raman scattering down to about 200 cm-1. Blocking of laser radiation to OD6 is enabled by coating both the distal and proximal tips.
