ABSTRACT:
In methods and apparatus for controlling the D.C. bias point of a nonlinear device, asymmetric envelope modulation is applied to an input signal, and the nonlinear device is driven by the asymmetric envelope-modulated signal and a D.C. bias signal. A nonlinear characteristic of the device is monitored at the modulation frequency, and the D.C. bias signal is controlled in response to the monitored characteristic so as to reduce the monitored characteristic at the modulation frequency. The methods and apparatus are particularly useful for controlling the D.C. bias point of semiconductor diode lasers, in which case the monitored characteristic can be the light output of the laser or the voltage across the laser.
