发明名称 METHOD OF CONTROLLING THE TURN OFF CHARACTERISTICS OF A VCSEL DIODE
摘要 <p>A drive circuitry that drives a vertical cavity surface emitting laser, or VCSEL (9) is provided. The drive circuitry includes a modulator (7), a negative peak timer (5) and a limiter (3). The negative peak timer (5) causes the modulator (7) to rapidly decrease the magnitude of the output signal of the modulator (7) to dissipate charge stored on the laser (9). Thus, the VCSEL (9) quickly turns off.</p>
