Paper Abstract

High-speed transmission optical devices and equipment often use a single-mode fiber as receiver or emitter. The fiber must be accurately aligned over five degrees of freedom with respect to an optical field. In this paper, we investigate a model-based approach which takes advantage of the properties of the optical coupling physical phenomenon. Using a Gaussian field approximation and an approximated solution of the overlap integral, two fundamental properties are first derived. Both are then validated by numerical simulations and experiments. A very simple alignment procedure is the proposed and tested experimentally using two single-mode fibers.
