Abstract :
A surface-enhanced Raman scattering (SERS) optical fiber sensor using biconical taper multi-mode fiber (MMF) is proposed. It is fabricated by fused elongating a multi-mode fiber and then coated the silver colloid on its waist. The Raman spectrum for R6G dye solution is measured and the detection sensitivity is 10-9 M.
