Abstract
Methods and systems for enhanced SERS sensing are disclosed, including generating electromagnetic radiation from a fiber laser; coupling the radiation to a SERS sensor comprising: a fiber comprising a first end and a second end, wherein the first end is coupled to the fiber laser and the second end is deposited with one or more metal nanoparticles; an in-line fiber grating integrated into the fiber between the first and the second end; a spectrometer configured to measure a spectrum produced by the in-line fiber grating; and a micro-processor configured to control the fiber laser and the spectrometer; exciting one or more molecules adsorbed on the surface of the one or more metal nanoparticles to generate a Raman signal; coupling the signal into the fiber; separating the signal into its wavelength components with the in-line fiber grating; and measuring the wavelength components with the spectrometer. Other embodiments are described and claimed.
