Abstract
Techniques and systems for controlling an optical switch array based on local and global optical monitoring and feedback controls. Each optical switch element 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 to maintain an overall alignment.
