OPTICAL TRANSMITTING APPARATUS AND METHOD, AND OPTICAL RECEIVING DEVICE AND METHOD

摘要

The invention relates to an optical transmitting apparatus, which performs an optical modulation on the signal to be transmitted using phases of two optical carriers having respective wavelengths, and transmits the modulated signal to an optical receiving device. The optical receiving device demodulates the phase-modulated optical signal through an amplitude modulation to detect the signal transmitted by the optical transmitting apparatus.
