BIREFRINGENT INTERLEAVER FOR WDM FIBER OPTIC COMMUNICATIONS

摘要

An interleaver device that interleaves and de-interleaves odd and even channels by rotating the polarization of the WDM channels. In de-interleaving, the polarization of the odd channels is rotated to a different angle than the polarization of the even channels, and the odd and even channels are then polarization mode separated. When interleaving, the even and odd channels are polarization mode combined, and the even and odd channels are then polarization rotated are rotated so that all channels have the same polarization.
