论文摘要
在这项贡献中，我们基于在绝缘体波导平台上的薄膜硅锂中的时空调制，模拟，设计和实验证明了基于时空调制的集成光学隔离器。我们使用两个级联的行驶波相调节器进行时空调制和一个环谐振器作为波长滤波器来抑制反向传播光的边带。这使我们能够实现27 dB的隔离。证明对反向传播光的抑制作用使该隔离器适合与III-V激光二极管的整合，并在绝缘子波导平台上的薄膜锂锂中的二膜锂中的掺杂型增益部分。
In this contribution, we simulate, design, and experimentally demonstrate an integrated optical isolator based on spatiotemporal modulation in the thin-film lithium niobate on insulator waveguide platform. We used two cascaded travelling wave phase modulators for spatiotemporal modulation and a ring resonator as a wavelength filter to suppress the sidebands of the reverse propagating light. This enabled us to achieve an isolation of 27 dB. The demonstrated suppression of the reverse propagating light makes such isolators suitable for the integration with III-V laser diodes and Erbium doped gain sections in the thin-film lithium niobate on insulator waveguide platform.
