Abstract
A driver circuit for a polarization scrambler () having a number of electrodes () is characterized in that the driver circuit comprises at least one pulse source () emitting a pulsed signal at a fundamental frequency, that the driver circuit further comprises a plurality of passive filter and matching circuits () for said number of electrodes () of said polarization scrambler (), wherein each passive filter and matching circuit () is designed for driving one or several of the electrodes (), and wherein each passive filter and matching circuit () is designed such that it filters out at least one harmonic mode frequency of said pulsed signal. The inventive driver circuit has a low power consumption and generates only few heat.
