ABSTRACT:
The present invention relates to A drive circuit can stabilize a bias voltage of an optical modulator to realize long distance transmission by preventing degradation of waveform, even if there is a dispersion on a characteristic of an electro-absorption modulator according to temperature and a secular change. The drive circuit supplies a driving voltage to an electro-absorption modulator which adsorbs a carrier light, depending on the driving voltage and outputting an intensity-modulated signal, and a peak value detector for detecting a peak value of a voltage at an anode of the electro-absorption modulator, and a bias current supplying circuit for supplying a bias current to control the driving voltage according to a difference between the peak value detected by the peak value detector and a predetermined value.
