OPTICAL TRANSMITTER/RECEIVER AND ITS CONTROLLING METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide an optical transmitter/receiver in which the maximum extinction ratio of an optical modulator can be obtained under given conditions. <P>SOLUTION: A specified amplitude side of input signals to an optical modulator 20 is made an amplitude modulation state. The level of the input signals is controlled so that the one amplitude side of the input signals is adapted to the minimum portion of the modulation characteristics curve of the optical modulator. <P>COPYRIGHT: (C)2004,JPO</p> |
