  • System and method for transmitting analog signals with a modulating retroreflector and hybrid amplitude and frequency modulation
    Patent number: 7715727
    Abstract: A system and method for encoding an analog input signal for optical transmission, including driving a voltage controlled oscillator with an analog input signal to produce a frequency modulated electrical signal having a frequency proportional to the amplitude of the input signal, and applying the frequency modulated electrical signal to a multiple quantum well modulating retroreflector. The retroreflector receives optical energy from a laser source and modulates the optical energy with the frequency modulated signal to produce an output optical signal.
