Low power driver circuit for a polarization scrambler

A driver circuit for a polarization scrambler ( 11 ) having a number of electrodes ( 17 ) is characterized in that the driver circuit comprises at least one pulse source ( 18 ) emitting a pulsed signal at a fundamental frequency, that the driver circuit further comprises a plurality of passive filter and matching circuits ( 19 ) for said number of electrodes ( 17 ) of said polarization scrambler ( 11 ), wherein each passive filter and matching circuit ( 19 ) is designed for driving one or several of the electrodes ( 17 ), and wherein each passive filter and matching circuit ( 19 ) 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.
