摘要

在本文中,我们模拟、设计并实验证明了基于时空调制的铌酸锂薄膜绝缘体波导平台集成光隔离器。我们使用两个级联行波相位调制器进行时空调制,并使用一个环形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。该隔离器对反向传播光的抑制作用使其适合于与III-V型激光二极管和掺铒增益部分在绝缘体波导平台上的铌酸锂薄膜中的集成。

Spatio-temporal isolator in lithium niobate on insulator
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.
