CONTROL APPARATUS AND METHODS IN PHOTONICS APPLICATIONS

摘要

Control apparatus and methods for photonic devices are disclosed. One or more detectors is used to monitor a functional state of a photonic device. Each detector is configured to receive a respective pair of optical signals from the photonic device and generate a detection signal proportional to a difference between the pair of optical signals. A controller generates control signal(s) for the photonic device based on the detection signal(s). The apparatus and methods may be used in optical switching applications to control multiple photonic devices configured as optical switches in order to implement a multi-channel optical switch fabric for a multi-channel optical switch.
