摘要

我们展示了一个集成的高q级联法布里-珀罗（FP）谐振器在铌酸锂绝缘体（LNOI）上，由多sagnac环路反射器实现，它是由飞秒激光光刻辅助化学机械抛光（CMP）制造的。与仅由两个Sagnac环反射器（slr）组成的谐振腔相比，由多个slr组成的级联谐振腔的Q因子显著增强。级联谐振器的负载Q因子测量为1.16 × 106，与相同材料平台上的当前状态相比，提高了五倍。

Integrated high-Q cascaded Fabry-Perot resonators based on lithium niobate Sagnac loop reflectors.

We demonstrated an integrated high-Q cascaded Fabry-Perot (FP) resonator on lithium niobate on insulator (LNOI) implemented by multi-Sagnac loop reflectors, which was fabricated by femtosecond laser photolithography-assisted chemo-mechanical polishing (CMP). Compared with the resonator that comprised only two Sagnac loop reflectors (SLRs), there is a significant Q factor enhancement in the cascaded resonator formed by multi-SLRs. The loaded Q factor of the cascaded resonator was measured to be 1.16 × 10⁶, a five-fold improvement compared to the state of the art on the same material platform.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
