Optical signal transmitter and method for controlling polarization multiplexed optical signal |
摘要 |
An optical signal transmitter includes: first outer modulator to generate first modulated optical signal, the first outer modulator including a pair of optical paths and a first phase shifter to give phase difference to the pair of optical paths; second outer modulator to generate second modulated optical signal, the second outer modulator including a pair of optical paths and a second phase shifter to give phase difference to the pair of optical paths; combiner to generate polarization multiplexed optical signal by combining the first and second modulated optical signals; phase controller to control the phase difference by the first phase shifter to A-Deltaphi and control the phase difference by the second phase shifter to A+Deltaphi; and power controller to control at least one of the first and second outer modulators based on AC component of the polarization multiplexed optical signal.
