Abstract: An optical transmitter that controls the extinction ratio by modulating a power level of an optical signal using a frequency spread tone. An electro-optic transducer driver generates an electrical signal that is to be converted into an optical signal. Meanwhile, a tone generator generates an electrical tone having a relatively narrow frequency spectrum. A frequency spreading circuit frequency spreads the electrical tone. A modulator modulates a power level of the electrical signal using the frequency spread electrical tone. An electro-optic transducer then converts the modulated electrical signal into a corresponding optical signal. An optoelectronic transducer recovers the modulated electrical signal by monitoring the optical signal. The tone is then recovered from the signal, and demodulated. The demodulated tone is then used to control the extinction ratio.
