摘要

提出了一种基于两个级联极化调制器(polm)和一个微波光子移相器实现可调载波与边带比(OCSR)和光单边带调制(OSSB)的方案。通过调整第二个PolM的直流偏置，可以实现两个功能之间的切换。进行了实验。实现了工作带宽为5 ~ 35ghz的OSSB调制信号，并演示了两个ocsr在-26 ~ 46db和-25 ~ 55db范围内可调的OSSB调制信号。当系统切换为微波光子移相器时，可以实现全360度相位调谐。该方案具有结构紧凑和双开关功能的特点，在微波光子学领域具有一定的应用前景。

A microwave photonic system with switchable functions based on cascaded polarization modulators

A novel scheme based on two cascaded polarization modulators (PolMs) is proposed to implement optical-single-sideband modulation (OSSB) with tunable carrier-to-sideband ratio (OCSR) and a microwave photonic phase shifter. Switching between the two functions can be realized by adjusting the DC bias of the second PolM. An experiment is carried out. OSSB modulated signals with an operation bandwidth from 5 to 35 GHz are achieved and two OSSB modulated signals with tunable OCSRs from -26 to 46 dB and from -25 to 55 dB are demonstrated. When the system is switched to be a microwave photonic phase shifter, a full 360 degree phase tuning range can be realized. The proposed scheme features a compact structure and dual switchable functions, which may find applications in microwave photonics.
