| Abstract(in English) | We propose a polarization-multiplexing QPSK modulator for synthesis of a 16QAM signal. The generation mechanism of 16QAM is based on an electro-optic vector digital-to-analog converter, which can generate optical multilevel signals from binary electric data sequences. This modulator is utilized a dual-polarization MZM, outputting two QPSK signals with orthogonal polarization. The QPSK signals are superposed by a polarizer, in which the amplitude ratio between them is precisely controlled by rotating the polarizer to arrange the 16 symbols equally. Generation of 40 Gb/s 16QAM with a bit error rate of 5.69×10^<-5> was successfully demonstrated using the modulator. |
