The application of ferrocene-based polymers as variable index materials is discussed. The refractive index of thin film of a particular polymer known as poly(methylphenylsilyeneferrocenylene) is examined during exposure to ammonia, nitrous oxide, nitric oxide, nitrogen, carbon dioxide, carbon monoxide, and argon. A maximum of 9% deviation in the refractive index of the polymer upon exposure to ammonia is observed. The theory of operation and fabrication of polymer-coated tapered optical fiber gas sensors are explained. Experimental data is presented showing qualitative response to ammonia and other gases.
