A drive circuitry that drives a vertical cavity surface emitting laser is provided. The drive circuitry includes a modulator, a negative peak timer and a limiter. The negative peak timer causes the modulator to rapidly decrease the magnitude of the output signal of the modulator to dissipate charge

A drive circuitry that drives a vertical cavity surface emitting laser is provided. The drive circuitry includes a modulator, a negative peak timer and a limiter. The negative peak timer causes the modulator to rapidly decrease the magnitude of the output signal of the modulator to dissipate charge stored on the laser. Thus, the vertical cavity surface emitting laser quickly turns off.
