Abstract
Raman spectroscopy is a powerful tool for detecting and identifying molecular structures and chemical bonds in materials. Diverse platforms have been developed to enhance spectroscopic sensitivity. We present a novel doubly enhanced Raman spectroscopy through an optoplasmonic microprobe configuration. The microprobe includes a high-Q whispering-gallery-mode microsphere resonator and nanoplasmonic structures on a substrate with samples sandwiched between them. The optoplasmonic hybrid modes can realize a two-order-of-magnitude improvement over traditional surface-enhanced Raman spectroscopies (SERS), such as commercial SERS test papers. Additionally, 2D Raman imaging is demonstrated by scanning the sample surfaces, showing a new tool for highly sensitive Raman spectroscopy imaging.
