Optical fibers coated with noble metal nanoparticles can therefore be used as SERS-based sensors for remote detection of molecular species. In this article, we report on the development of an optical fiber SERS sensor capable to operate on a range of excitation wavelengths from the visible to the near-infrared. We introduce a quasistatic chemical etching protocol to engineer the tip shape and investigate the effects of the tip shape on the sensor performances.
