Abstract

Fiber SERS (surface enhanced Raman scattering) sensors have attracted significant interest in molecule sensing. In this paper, we briefly review our previous work on various configurations for fiber SERS probes, including side-polished fibers and various photonic crystal fibers (PCFs). In addition, we will report our recent experiments on a double substrate "sandwich" structure for fiber SERS probe. The approach is to coat one SERS substrate on the tip of a multimode fiber and mix the second substrate in solution with the target analyte molecules. Upon dipping the coated fiber probe into the solution, randomly formed structures of the two substrates will sandwich the analyte molecules in between. Our results show that the "sandwich" configuration exhibits significantly higher sensitivity than direct SERS detection.
