<p>Techniques and systems for controlling an optical switch array (1700) based on local and global optical monitoring and feedback controls. Each optical switch element (1724, 1734) includes a local optical monitoring mechanism to form a local feedback control to lock the switch element at a desired orientation. The global optical monitoring is used to adjust at least one switch element in the path of the signal beam (1712) to maintain an overall alignment.</p> |
