    Abstract: An optical signal router for communication systems is described. The optical signal router includes a switch driver that generates a modulation drive signal containing a linear combination of a DC offset voltage and at least three electrical signals. In one embodiment, each of the at least three electrical signals has a frequency that is a unique integral multiple of a bit-rate. The optical signal router also includes an optical switch having an electrical modulation input that is electrically coupled to the output of the switch driver. The optical switch also includes an optical input that receives a time-division multiplexed optical signal including a plurality of optical subchannels. In one embodiment, each of the plurality of optical subchannels includes the bit-rate. The optical switch routes a subset of the plurality of optical subchannels to an optical output in response to the modulation drive signal.

    Abstract: An apparatus and method for demultiplexing a time and polarization multiplexed signal are described. The multiplexed signal is a combination of component signals, each of which is characterized by a polarization. The demultiplexer of the system includes an input interface over which the signal is received. A polarization demultiplexer receives the multiplexed signal and polarization demultiplexes the signal. Next, a time-demultiplexing stage time-demultiplexes the polarization-demultiplexed signal to recover the original component signals. A clock recovery circuit recovers the clock from the polarization-demultiplexed signal before time demultiplexing.

    Abstract: A bit interleaved polarization multiplexer is described that includes a first and a second modulator. The first and the second modulator modulate a first and a second electrical modulation signal, respectively, onto an optical signal and generate a modulated optical pulse train at a first and a second optical output, respectively. An optical beam combiner combines the modulated optical bit stream generated by the first and the second modulators into a polarization multiplexed optical pulse train. A relative position of each pulse in the polarization multiplexed optical pulse train is determined by an optical path length propagated by the pulse and a relative order of each pulse in the polarization multiplexed optical pulse train is determined by a relative phase of the modulation signal that generated the pulse.
