Abstract
An optical transmitter device includes a laser source, a driving circuit, and an optical modulator. The driving circuit is connected to the laser source. The driving circuit includes a thermistor configured for compensating the temperature variation of the laser source to stabilize the frequency of a laser beam output from the laser source. The optical modulator is configured for modulating the laser beam to form a plurality of second laser beams which have different frequencies.
