Abstract
A low-cost optical fiber sensor to detect volatile organic compounds has be en developed. Changes of up to 13.5 dB in the transmitted optical power hav e been detected with different concentrations of acetone and dichloromethan e vapors. The device uses a standard single-mode fiber. The sensing mechani sm relies on a vapor-induced refractive index change in a film of a vapochr omic material deposited on the thinner region of a tapered fiber.
