我们报告的50个12.5 GHz的间隔的光载波的产生与高功率平坦度和稳定性，通过使用单边带（SSB）调制器为基础的循环频率移位器（RFS）。产生的载波的峰峰值功率差和RMS功率差分别为2.5和0.3 dB。我们还通过实验研究了实施缺陷对所产生的载波的平坦度的影响。影响载波平坦度的重要因素是单边带调制器同相（I）和正交（Q）驱动信号的幅度平衡、I和Q信号之间的时间不对准、单边带调制器/2相位偏置的精度以及RFS中偏振对准的稳定性。通过仔细控制前面提到的所有因素，我们获得了50个频率锁定载波的稳定操作，表明基于SSB调制器的RFS是一种很有前途的技术，为未来的太比特每秒多载波传输。
We report the generation of fifty 12.5-GHz-spaced optical carriers with high power flatness and stability by using a single-side band (SSB) modulator-based recirculating frequency shifter (RFS). The peak-to-peak power difference and the RMS power difference of the generated carriers are 2.5 and 0.3 dB, respectively. We also experimentally investigate the impact of implementation imperfections on the flatness of the generated carriers. The important factors that contribute to the flatness of the generated carriers are found to be the amplitude balance of two inphase (I) and quadrature (Q) drive signals for the SSB modulator, the time misalignment between the I and Q signals, the accuracy of the /2 phase bias of the SSB modulator and the stability of the polarization alignment in the RFS. By carefully controlling all the factors mentioned earlier, we obtain stable operation of 50 frequency-locked carriers; showing that the SSB modulator-based RFS is a promising technique for future terabit per second multicarrier transmission.
