Abstract

Optical fibers are popular devices for measuring a variety of physical phenomena; pressure, temperature, magnetic flux, etc. Analysis of optical fiber sensors has been limited to the classical Lame' solution for conditions of plane strain. Finite element analysis can remove the plane strain limitation and allows the evaluation of realistic sensor configurations. This paper dis-cusses the application of analog techniques to the modeling of wave propagation in a single mode quartz fiber using a finite element code. The results are compared to published data for pressure and temperature sensors.
