Optimal refractive index profile design for a pair of optical fibre-based devices

摘要

This paper presents an application of nonlinear optimization in the design of two particular optical fibre-based devices, namely an evanescent field sensor and a communications fibre. This work formalizes and improves upon adhoc methods employed in the optics literature and results in some quite novel device designs of current interest to the photonics community. The tools applied include dynamic programming and an implicit Markov chain approximation method for numerically solving the attendant dynamic programming equation.
