Abstract
This paper presents an application of numerical optimization via dynamic programming in the design of a refractive index profile for an optical fibre-based evanescent field sensor. The designed sensor delivers approximately 15% of the total propagating electromagetic field power to the surrounding environment for sensing purposes, representing a substantial improvement over previous ad-hoc designs delivering at most 9% (Gibson et al, 2001).
