Abstract
We present design, analysis and characterization of surface- micromachined mirrors developed for fiber-optical cross-connects (OXCs). These mirrors are controlled by electrostatic microactuators, and are optimized for our beam-steering OXC switch architecture. Their geometry leads to high-density switch matrices, and the absence of frictional hinges in their actuation mechanism allows highly repeatable operation. This mirror structure features an adjustable maximum deflection angle that can be set during initial assembly or dynamically varied by integration with a standard surface-micromachined linear actuator. A commercial three-layer polysilicon surface- micromachining process is used for fabrication of the micromirrors.
