    摘要： Based on binary transmission data 12, a receiver 11 emits electromagnetic waves 13 with modulated plane of polarization into a free space 16. The data propagates along the free space 16 as the azimuth of the plane of polarization. A receiver 17 accepts the electromagnetic wave 13 with modulated plane of polarization discriminates the data based on the state of the plane of polarization, and outputs the binary received data 18. The data and the clock data are transmitted from a plurality of light-emitting units with different polarization states or wavelengths to omit PLL circuits.
