In this paper, we present a 1x2 electro-optical switch based on a 1x2 polarization beam splitter (PBS), a 2x2 polarization beam
combiner (PBC) and two TE/TM polarization converters. By applying a voltage of 0/+5 V simultaneously on the two converters,
an optical signal is routed to the cross port or to the bar port. We have used the light polarization principle to eliminate the
polarization dependent loss. The total insertion loss obtained through simulation is 0.6 dB, while the switching time is estimated
to 20 μs. The estimated extinction ratio of this switch is 30 dB. We present also on this paper, an all-optical 2x1 multiplexer based
also on PBSs, PBCs and a polarization controller. The insertion loss found by simulation is 0.5 dB. The demultiplexing function
is done by placing only a 1x2 polarization beam splitter after this multiplexer. The two proposed devices operate on the 1550 nm
wavelength with a 40 nm pass band.
