Method of and a device for polarization-independent optical demultiplexing |
摘要 |
This invention concerns a method of and a device for optical demultiplexing that are based on the four wave mixing between the signals to be demultiplexed and pump signals. The two signals are fed into a polarization maintaining fiber (14), which divides them into two components with orthogonal polarization, separated in time; and the four wave mixing is performed separately on the two components, thereby originating two separate signals that are polarization-rotated and re-combined. (FIG. 1).
