波导畸变
Furthermore, a straight waveguide is added before the tapered waveguide to decrease distortion in mode fields, which results from the off centering of the peak field because of the bend of the input waveguides. According to the solution presented above, a novel AWG is implemented.
此外,考虑到输入波导弯曲导致的光场峰值偏离波导中心,一细直波导被用来减小由此导致的场型畸变。
But wrinkling, distortion, tension crack etc are easily produced during the rotary draw bending process, especially the wrinkling seriously influence the quality of rectangular waveguide.
但在薄壁矩形管绕弯成形过程中极易产生失稳起皱、截面畸变、拉裂等缺陷;特别是失稳起皱,严重地影响着矩形波导管的弯曲成形质量。
