在 15GHz 附近实验演示了使用单个 RF 调制信号操作的高速光学抑制载波单边带调制器/光学移频器。三路波导干涉仪增强了电光相位调制产生的一个光边带，同时抑制了另一个光边带和载波。通过在铁电材料基板中使用偏振反转结构，还可以实现对光调制相位的任意控制。这些技术产生了紧凑型光学抑制载波单边带调制器/光学移频器，在准毫米波/毫米波频率范围内使用单个射频调制信号进行操作
A high-speed optical suppressed-carrier single side-band modulator/optical frequency shifter operated with a single RF modulation signal was experimentally demonstrated around 15GHz. One optical side-band generated by electro-optic phase modulation was enhanced but the other optical side-band and carrier were suppressed at the same time by using the three-branch waveguide interferometer. Arbitrary control of the phase of optical modulation was also obtainable by using the polarization-reversed structure in a ferroelectric material substrate. These techniques lead to a compact optical suppressed-carrier single side-band modulator/optical frequency shifter operated with a single RF modulation signal at quasi-millimeter-wave/millimeter-wave frequency ranges
