  • Control system for an optical modulator
    Patent number: 4460249
    Abstract: A control system for a laser-intensity-modulator system to maintain the modulated component of the output beam at a constant amplitude. The electro-optical modulator has a resonant driving circuit supplied by a voltage controlled oscillator. A portion of the output beam is detected and a control signal representative of the amplitude of the modulated component is derived and supplied to the oscillator in addition to the normal bias voltage which sets the nominal frequency. This stabilizes the amplitude of the modulated component in the output beam.
