1. An optical signal transmission system, comprising:
- a transmitter that phase-modulates two optical signals of a same frequency by asymmetrically chirping the two optical signals, combines the two optical signals that have been phase-modulated as polarization components according to polarization multiplexing, and transmits an optical signal that has been combined and obtained; and
a receiver that receives said optical signal from said transmitter, compresses pulses of at least one of the polarization components of the optical signal, and splits the optical signal into two polarization components.
