| titleOfInvention | Optical generating device and method for multi-channel arbitrary system phase coding signals |
| abstract | The application discloses multichannel arbitrary system phase code signal optics produces device and method, includes: the transmitting unit generates an optical signal with a certain polarization direction; the modulation unit modulates the optical signal under the control of the radio frequency driving signal and the main bias direct current voltage to generate a positive and negative second-order sideband with orthogonal polarization; the first light splitting unit divides the positive and negative second-order sidebands generated by the modulation unit into two paths of positive and negative second-order sidebands which are orthogonal in polarization respectively; the second light splitting unit separates positive and negative second-order sidebands output by the first output end of the first light splitting unit, loads coded signals of any system respectively, and outputs optical signals; the output unit couples the optical signals output by the first light splitting unit and the second light splitting unit, then divides the optical signals into two paths to respectively perform photoelectric conversion, and simultaneously outputs two paths of arbitrary system phase coding microwave signals. The method and the device can improve the transmission capacity and the frequency spectrum utilization rate of the system, and the generated signal has the advantages of large-range adjustable frequency, low noise, large pulse compression ratio and the like. |
