Abstract
A work station included in a burst optical communication system has a semiconductor laser for performing light emission corresponding to a data pulse signal to be transmitted, and a bias generator for biasing the laser in accordance with a uni-directional power control technique. When an actual light output is detected to be decreased in accordance with a detection signal from a photodetector for detecting the actual light output emitted from the laser, a logic circuit in a bias generator charges a capacitor, thereby increasing the bias current supplied to the laser. However, when the actual light output exceeds an optimal reference level, the bias current stops increasing but is not decreased.
