Abstract:
An optical polarization multiplexing apparatus, comprising:a first polarization filter through which a first optical signal passes; a second polarization filter through which a second optical signal passes; an optical adder in communication with the first polarization filter and the second polarization filter to receive the first optical signal and the second optical signal, the optical adder adding and outputting an optical transmission signal having a first polarization orientation component and a second polarization orientation component; an optical splitter in communication with an output of the optical adder to receive the optical transmission signal; a third polarization filter in communication with the optical splitter, the third polarization filter recovering the first optical signal; a fourth polarization filter in communication with the optical splitter, the fourth polarization filter recovering the second optical signal; an optical data link between the optical adder and the optical splitter; and a control unit connected to control an orientation of the third and the fourth polarization filters to recover the first and the second optical signals, respectively.
