| 1. A receiver for an optical time division multiplexed pulse train in which the pulses have alternating polarizations, the
receiver comprising:
a) a polarization insensitive optical switch for isolating optical pulses within the pulse train, and
b) a polarization selective element for separating from the isolated pulses at least one component that has a single polarization.
