Interferometer for all-optical timing recovery |
摘要 |
<p>Optical timing detection, for phase comparison of optical signals, or clock recovery is achieved by arranging an interferometer to be responsible to data transitions. A pulse train is fed into both arms of the interferometer. An optical amplifier (20) enables the interference condition to be changed when the data is fed into one arm. The output changed if the data transitions lose synchronisation with the pulse train. <IMAGE></p> |
