Abstract

The effects of water are eliminated from an optical waveguide chemical sensor by applying a hydrophilic coating which creates a pseudo water jacket. The hydrophilic coating absorbs water so that the waveguide sees a constant refractive index. The hydrophilic coating can reach equilibrium conditions in a high relative humidity environment or can be pretreated by exposure to water in a low relative humidity environment. A variety of hydrophilic polymers can be used.
