  • Overmodulation protection for amplitude modulated laser diode
    Patent number: 5140603
    Abstract: A laser diode protection circuit which monitors the r.f. modulation level of the input modulating signal to the laser diode and disconnects the laser diode from the r.f. modulating signal when it exceeds an acceptable level. The circuit further monitors the output of the d.c. power supply which provides the d.c. bias current to the laser diode. The circuit disconnects the laser diode from the r.f. modulating signal when the output of the power supply falls below an acceptable level.
