Abstract

A powerful angle-resolved method is presented for characterizing ray-group attenuation in cylindrical multimode waveguides that can be used for the design optimization of fiber-optic sensors. It is supported by an in-depth theoretical model that is accurate yet simple for describing the propagation of meridional and skew rays in passive cylindrical multimode waveguides. In particular, the transmitted power of different ray groups and the near- and far-field profiles can be simulated. Also, the individual parameters contributing to the attenuation of light can be extracted from the experimental results.
