We present a high-performance radio frequency (RF) photonic bandpass filter enabled by combining on-chip Brillouin scattering with a suppressed carrier phase modulation scheme. We achieve a low RF loss of 5 dB and a large stopband rejection of more than 40 dB, which represents a significant improvement of 20 dB to the RF passband gain and 31 dB to the RF rejection ratio over traditional modulation schemes under the same optical power consumption. We further demonstrate filter reconfigurability including multiple passbands, wide frequency (1–20 GHz), and bandwidth tunability (30–350 MHz) without compromising the RF performance.

低射频损耗和大抑制率可重构基于布里渊的射频光子带通滤波器。

我们提出了一种高性能射频（RF）光子带通滤波器，通过将片上布里渊散射与抑制的载波相位调制方案相结合来实现。我们实现了5 dB的低RF损耗和超过40 dB的大阻带抑制，这表示在相同光功率下，与传统的调制方案相比，RF通带增益显着提高了20 dB，RF抑制比显着提高了31 dB消费。我们进一步展示了滤波器的可重新配置性，包括多个通带，宽频率（1–20 GHz）和带宽可调性（30–350 MHz），而不会损害RF性能。
