  • Bias circuit of electro-absorption modulated laser and calibration method thereof
    Patent number: 8718107
    Abstract: A bias circuit of an electro-absorption modulated laser and a calibration method thereof are provided. The bias circuit includes a drive circuit and a direct current bias voltage circuit. The drive circuit is used for providing a forward bias voltage to a laser diode in the electro-absorption modulated laser to generate laser. The direct current bias voltage circuit is connected to a cathode of an electro-absorption modulator in the electro-absorption modulated laser, and provides a positive direct current bias voltage to the cathode to enable the reverse bias voltage of the electro-absorption modulator to fall within the range of modulation. When the reverse bias voltage falls within the range of modulation, the electro-absorption modulator utilizes the laser generated by the laser diode as optical carrier wave, modulates the optical carrier wave with the modulation voltage, and outputs a modulated optical signal.
