Abstract

Optical switching fabrics based on 3D MEMS technology potentially offer a scalable solution for the cross-connect network element. The design, integration, and assembly of high port count switch fabrics that can operate under a low loss budget, fast switching time, superb mirror stability and long-term reliable packaging present important engineering challenges. In this paper we describe the major optical, mechanical, MEMS and electronic design considerations as well as their critical inter-relationships in the development of 3D MEMS-based optical cross-connect fabrics. The specifications placed on the various components in order to meet the overall system tolerances and loss budget will be discussed. In addition, we will address the short-term (sub-millisecond) control and long-term (hours and up) stability of the optical connections due to mirror stability and long-term mechanical drifts. We will also present our thoughts regarding the solutions to those problems.
