Abstract
In this Small Business Innovative Research (SBIR) effort, Nikira Labs Inc. proposes to develop a compact Raman fiber optic probe with inline spectral filtering that improves fiber-coupled Raman measurements by filtering out Raman scattering from the excitation fiber and elastically scattered laser light from the collection fibers. The technology will enable compact fiber probes for Raman studies in vivo and other difficult to access areas. It will complement existing Raman spectroscopy efforts that are ongoing at the National Institute of Standard and Technology (NIST) including tissue studies and broadband coherent anti-stokes Raman scattering measurements. In Phase I, Nikira Labs demonstrated technical feasibility by deploying semi-soft materials on single-mode fiber, multi-mode fibers, and fiber optic bundles. In Phase II, we will work to improve the coating process and fabricate higher quality, hard oxide dielectric films. These coatings will be deposited on a Raman fiber probe to generate a compact Raman fiber optic probe with inline spectral filtering. At the conclusion of this effort, several test pieces will be delivered to NIST for continued research and implementation in their Raman programs.
