Abstract
A localized and distributive optical switching control system is separated into three localized systems: a sensor system, a processor system, and a position driver system. The sensor system detects the light transmission efficiency from the input port to the output port, and sends an error signal to the processor system; the processor system processes the error signal and, based upon predefined compensators and control algorithms, generates a control output signal to rectify the error to the sending and/or receiving position driver(s); the position driver(s) receives the control output signal then repositions the sending and/or receiving mirror(s) to the desired position for optimum signal transmission. The amount of communication data and the amount of routing paths between components are reduced, thus decreasing system reaction time and heat generated, allowing controls to be installed on smaller circuits, such as ASIC, and the arrays to be placed closer together.
