A polarization based optical switch capable of redirecting light signals
to a plurality of different output locations. The optical switch utilizes
polarization beam splitters to separate each optical channel into
multiple polarization portions. Reflection members are used to redirect
some of the polarization portions. Polarization rotators are capable of
manipulating the plane of polarization of the polarization portions which
will determine which of the output locations each optical channel
transmits through. Another polarization beam splitter is used to
recombine the polarization portions and direct them to one of the output
locations depending on their respective planes of polarization.
