摘要
Optical-fiber transmission system with heterodyne coherent detection in which, at the transmitting side, the polarization of an optical carrier is modulated, and at the receiving side the beam resulting from a combination of the modulated beam and a beam emitted from a local oscillator is split into two orthogonally-polarized components. The two optical signals are detected and sent to an electronic mixer which receives the two components and carries out a synchronous demodulation eliminating the effects of the linewidth of the source and of the local oscillator.
