| 摘要 |
<p>The invention provides an optical device (100) for demultiplexing at least two RZ optical signals (i1, i2, i3), each having a distinct non-zero intensity, said signals belonging to a given transmission channel having a given carrier frequency, and the device comprising: . means (12) for shifting said signals spectrally as a function of their intensities, thereby giving rise to shifted signals, each presenting at least one distinct shifted carrier frequency; and . means (14) for extracting said shifted signals as a function of their shifted carrier frequencies. <IMAGE></p> |
