Methods and devices for optimizing the operation of a semiconductor optical modulator

Patent Number: 9,083,460

Official Filing: View the Complete Patent
Abstract: A semiconductor-based optical modulator includes a control loop to control and optimize the modulator's operation for relatively high data rates (above 1 GHz) and/or relatively high voltage levels. Both the amplitude of the modulator's driving voltage and the bias of the driving voltage may be adjusted using the control loop. Such adjustments help to optimize the operation of the modulator by reducing the number of errors present in a modulated data stream.
