Title: | Chemical sensing with microbent optical fiber |

Abstract: | We propose and demonstrate the possibility of using a permanently microbent bare optical fiber for detecting
chemical species. Two detection schemes, viz., a bright-field detection scheme (for the core modes), and a
dark-field detection scheme (for the cladding modes) have been employed to produce a fiber-optic sensor. The
sensor described here is sensitive enough to detect concentrations as low as nanomoles per liter of a chemical
species, with a dynamic range of more than 6 orders of magnitude. |
