Abstract

The method of parallel information transmission through an optical communication line by single semiconductor laser, coupled to an external multi mirror cavity, is proposed. The method is based upon the theoretically predicted possibility of each mode independent excitation within the laser coupled to external multi mirror cavity multi mode spectrum. The experiment was accomplished on arbitrary two-digit binary sequence transmission. The output signal and noise properties of the transmitter were investigated in both channels simultaneously. It was shown that mode hopping of the transmitter is the main source of noise in the transmission line. The possibility of mode hopping noise reduction by low bias current harmonic modulation was demonstrated.
