Paper Abstract

A novel humidity optical fiber sensor have been developed using an hygroscopic material, deposited on the thinner zone of a biconically tapered single mode optical fiber. Relative humidity variations form 40 percent to 90 percent have been detected producing up to 5dB optical power change.
