SHUNT DRIVER CIRCUIT FOR SEMICONDUCTOR LASER DIODE |
摘要 |
A driver circuit for the laser diode is disclosed. The driver circuit has the shunt configuration with a switching transistor connected in parallel to the laser diode to shunt the current flowing in the laser diode. In the present invention, the bias for the switching transistor is varied as the operating temperature of the laser diode. In addition, the gate bias for the switching transistor is compensated for the temperature dependence of the switching transistor.
