An electro-optic modulator (10) has its capacitance incorporated in the resonant circuit of an RF oscillator. Such a modulator may be supplied with optical power from an unmodulated optical source (13) to form an optical soliton pulse generator. Alternatively the modulator may be supplied with a digitally modulated optical soliton pulse train and the frequency and phase of the RF oscillator locked to that of the clock component of that pulse train to provide retiming and reshaping of its solitons. The RF oscillator may be voltage-controlled. The invention reduces the drive voltage requirements of the RF oscillator. <IMAGE> |
