Abstract
An optical fiber humidity sensor was fabricated forming a nanometer-scale F abry-Perot interferometer by using the Ionic Self-Assembly Monolayer (ISAM) method. The materials used were Poly R-478 and poly(diallyldimethyl ammoni um chloride). Taking advantage of the precision that the ISAM method can ac hieve in controlling the length of the nano cavity, the length was fit to o btain a maximum variation of 8.7dB of reflected optical power between 11.3% and 85% RH. The sensor exhibited a fast response time and was able to moni tor the human breathing.
