我们从理论上证明了传统的马赫-曾德尔调制器可以产生具有良好光谱平坦度的光频梳。该调制器由不同幅值的大幅正弦信号非对称双重驱动。对获得光谱平坦度的驱动条件进行了解析推导和优化，得到了一个简单的公式。该公式还预测了生成的频率梳的转换效率和带宽。(C) 2007年美国光学学会
We theoretically prove that a conventional Mach-Zehnder modulator can generate an optical frequency comb with excellent spectral flatness. The modulator is asymmetrically dual driven by large amplitude sinusoidal signals with different amplitudes. The driving condition to obtain spectral flatness is analytically derived and optimized, yielding a simple formula. This formula also predicts the conversion efficiency and bandwidth of the generated frequency comb. (C) 2007 Optical Society of America
