Abstract: The present invention relates to an optical communication system and an optical transmission device. By changing the ratio between the first segment and the segment or/and the amplitude of the second segment, the digital signal is modulated and transmitted in the form of an optical signal. Then a solar panel, which is used as the receiver for the optical signal, can receive the optical signal and give directly the one or more digital signal without demodulation. Thereby, the costs of using a solar panel as the optical receiver may be reduced and the transmission rate may be enhanced.
