Paper Abstract

This paper investigates a method of producing internal mirrors for Intrinsic Fabry-Perot Sensors that have the potential for improving sensor strength. This approach is based on deposited mirrors on only the core of the fiber. Finite Element stress analysis and reflectivity modeling were used to determine appropriate coating thicknesses. TiO2 sol-gels coatings were then developed to deliver the exact thicknesses and optical properties needed for a thin film partially reflective mirror. A reverse photo resist masking method was developed in order to selectively deposit the TiO2 on the core. The results presented in this paper suggest that the core mirror concept shows promise, but that much work is still required to complete its development.
