Stabilization of a multi-channel optical signal transmitter through correlation feedback

摘要: Methods and apparatus for stabilizing or otherwise controlling optical signal power levels in a multi-channel communication system. A is detected single receiver, the resulting supplied to correlator. The correlator correlates with data associated particular channel be controlled order generate measure of channel. utilized feedback control loop an level may by mixing RF mixer, multiplying form unique identifier channel, using other suitable correlation techniques. processor used process which applied current source generating multi-frequency laser source. sequentially monitor each multiple channels same receiver
