Abstract:
A transmitter transmitting a polarization multiplexed optical signal, includes: a light source; a generating unit configured to split a light of the light source into first and second polarized lights, optically modulate the first and second polarized lights based on an electric data signal, and multiplex the first polarized light optically-modulated and the second polarized light optically-modulated to generate the polarization multiplexed optical signal; and a coupling unit configured to couple a first reference light having a frequency different from a frequency of the light of the light source with the first polarized light and couple a second reference light having a frequency different from the frequency of the light of the light source with the second polarized light, wherein the first reference light and the second reference light have different frequencies.

Claim (Index 4):
A receiver receiving a polarization multiplexed optical signal in which a first polarized light and a second polarized light are multiplexed, wherein\n the first polarized light contains a first signal light and a first reference light, a first signal being superimposed on the first signal light, the first signal light having a predetermined frequency, the first reference light having a frequency different from that of the first signal light, the second polarized light contains a second signal light and a second reference light, a second signal being superimposed on the second signal light, the second signal light having the predetermined frequency, the second reference light having a frequency different from those of the second signal light and the first reference light, and the receiver comprises:\n a polarization demultiplexing unit configured to demultiplex the first polarized light and the second polarized light from the polarization multiplexed optical signal, \n a first conversion unit configured to convert the first polarized light to a first electric signal; \n a second conversion unit configured to convert the second polarized light to a second electric signal; \n a first frequency shift unit configured to generate a first shift signal by shifting a frequency of the first electric signal based on the frequency of the first reference light, and generate a second shift signal by shifting the frequency of the first electric signal based on the frequency of the second reference light; \n a second frequency shift unit configured to generate a third shift signal by shifting a frequency of the second electric signal based on the frequency of the first reference light, and generate a fourth shift signal by shifting the frequency of the second electric signal based on the frequency of the second reference light; and \n an extraction unit configured to extract the first signal and the second signal from the first shift signal, the second shift signal, the third shift signal, and the fourth shift signal.
