摘要 |
To drive a single-mode laser device using a differential-pair output stage, collector terminals of transistors forming the differential-pair must be maintained at a predetermined potential. Since the potential dropped across the laser device is only about 1V, a Schottky diode connected between a cathode of the laser device and a second supply rail raises the cathode about 0.5V above the voltage of the second supply rail.
