We review recent work on narrowband orthogonally polarized optical RF single sideband generators as well as dual-channel equalization, both based on high-Q integrated ring resonators. The devices operate in the optical telecommunications C-band and enable RF operation over a range of either fixed or thermally tuneable frequencies. They operate via TE/TM mode birefringence in the resonator. We achieve a very large dynamic tuning range of over 55 dB for both the optical carrier-to-sideband ratio and the dual-channel RF equalization for both the fixed and tunable devices.

具有集成环形谐振器的正交偏振 RF 光学单边带生成

我们回顾了最近关于窄带正交偏振光射频单边带发生器以及双通道均衡的工作，两者均基于高Q集成环形谐振器。这些设备在光通信 C 波段中运行，并支持在固定或热可调频率范围内进行射频操作。它们通过谐振器中的 TE/TM 模式双折射工作。我们为固定和可调谐设备的光载边带比和双通道射频均衡实现了超过 55 dB 的非常大的动态调谐范围。
