| 摘要 |
The present invention relates to a traveling-wave photodetector (10; 22; 30), which comprises: a substrate (16); a light propagation medium (12) located on said substrate (16); a light absorbing medium (14) located on said substrate (16) and separated from said light propagation medium (12), said light absorbing medium (14) for absorbing an electrical signal (E(x)) generated by light propagating through said photodetector (10; 22; 30); and at least one electrode (18) located on said light absorbing medium (14) for transmitting said electrical signal (E (x)) (Fig. 3). <IMAGE> |
