    摘要: An apparatus controls the optical output intensity of a laser diode 52 used in an optical communication system. The laser diode 52 receives current from a pulse current supply 74 and a bias current supply 72. The optical output intensity of the laser diode 52 is controlled via a closed bias current control loop that includes a photodiode 50, which supplies a signal having a magnitude correlative to the optical output intensity of the laser diode 52. The closed bias current control loop monitors the trough level of the photodiode output to regulate the bias current supply 72. Thus, the output of the photodiode 50 is delivered to a means 56 for detecting the magnitude corresponding to the minimum magnitude of the optical output of the laser diode 52. The voltage corresponding to this detected low level is compared to a preselected voltage level V.sub.r and the difference in the two signals is delivered to the bias current supply through an integration circuit 66. Thus, as the optical output intensity of the laser diode 52 shifts with temperature or age degradation, the bias current supply correspondingly increases the current delivered to the laser diode 52 in order to maintain a constant optical output intensity.
