引力波探测器中使用的谐振边带提取需要激光的幅度调制。电光相位调制器的幅度调制是通过干涉相位幅度转换来实现的。虽然获得了两个相位相反的调制输出，但通常只利用其中之一而放弃另一个。重新利用这些废弃的光可以提高调制的功率效率。这可以通过使用延迟线反转一个输出的调制相位并将其相干地添加到另一个输出来实现。此外，该系统选择高效工作点并在线性范围内调制光。我们证明，调制系统可以在仅由光学元件损耗引起的功率损耗下运行。
Amplitude modulation of laser light is required for resonant sideband extraction employed in gravitational-wave detectors. Amplitude modulation with electro-optic phase modulators is realized by interferometric phase-to-amplitude conversion. Although two outputs modulated at opposite phases to each other are obtained, usually only one of them is utilized and the other is abandoned. The reuse of this abandoned light improves the power efficiency of the modulation. This can be realized by inverting the modulation phase of one output with a delay line and adding it to the other coherently. Moreover, this system selects a high-efficiency operating point and modulates the light in a linear range. We demonstrate that the modulation system can be operated with a power loss that is due only to the losses of the optical components.
