| Popis: | The electric field distribution of Gaussian beam and properties of Cassegrain optical antenna are discussed and their images have been simulated. By analysis of Cassegrain optical antenna with collimation and off-axis circumstance, laser power distribution and the curve of coupling efficiency are obtained. The question of spatial light to multimode fiber coupling efficiency with alignment and off-axis are researched. At last, taking into account off-axis situation of Cassegrain and laser beam to multimode fiber, the coupling efficiency of the whole system is discussed. These researches are necessary and useful for increasing spatial light to multimode fiber coupling efficiency. |
