Abstract
PURPOSE:To offer an optical multiplex communication method which can improve simply the multiplicity by executing the multiplexing transmission by loading the communication information as a carrier wave at every light beam whose wavelength and polarized wave the different, demultiplexing it at every light beam, and receiving each communication information. CONSTITUTION:According to the titled method, the wavelength multiplex communication is executed by using a light beam whose wavelength and polarization are different, by considering a difference of not only the wavelength but the polarized wave, and even by a simple comparison, the multiplicity of two times can be obtained. For instance, in case of utilizing light beams of two kinds of wavelengths lambda1, lambda2, when the light beams of lambda1 and lambda2 are polarized waves of two each, respectively, for instance, linearly polarized light beams, they have polarized waves of a (p) wave and an (s) wave whose polarized light directions are different. Therefore, by combining them, four kinds of light beams can exist as carrier waves. There four kinds of light beams emitted from laser diodes 21-24 are loaded with communication information, based on modulation power source 25-28, respectively, multiplexed by a multiplexer 29, brought to multiplex communication by an optical fiber transmission device 30, separated by a demultiplexer 31 and photodetected by photodetectors 32-35.
