  • Vertical cavity surface emitting laser feedback system and method
    Patent number: 5812582
    Abstract: An vertical cavity surface emitting laser feedback system is provided which has a vertical cavity surface emitting laser for emitting a specific amount of optical radiation. A portion of the optical radiation is received by a detection means which is used to generate a feedback signal that corresponds to the amount of optical radiation being emitted by the vertical cavity surface emitting laser.

  • Optoelectronic transceiver module laser diode stabilizer and bias control method
    Patent number: 5638390
    Abstract: A power stabilizer for maintaining a constant level of output power from a laser transmitter. The laser transmitter has a laser diode which produces a optical output which corresponds to the level of bias current received. In addition, the laser transmitter has a photodiode which produces a feedback signal which corresponds to the optical output power being produced by the laser diode. Furthermore, the power stabilizer consists of a digitally controlled potentiometer for producing a reference input signal and an op-amp for comparing the feedback signal and the reference input signal to produce a control signal to supply bias current.
