摘要

本文描述了1520 ~ 1630 nm范围内等离子体光栅和波导的数值模拟和实验表征结果。为了提高等离子体光栅的耦合效率，利用透镜光学探针在金结构表面包裹了一层630 nm厚的四乙基硅酸盐层。我们实验证明了金输入/输出等离子体光栅，每个光栅的效率约为- 3.8±0.2 dB。等离子体模在金波导表面传播的损耗为0.14±0.02 dB / μm。这项工作的目的是研究集成等离子体结构，以发展混合光子-等离子体集成技术。

High-efficiency and easy-to-fabricate integrated plasmonic grating couplers for the telecommunication wavelength range

The paper describes results of the numerical simulation and experimental characterization of plasmonic gratings and waveguides in the optical range of 1520 – 1630 nm. Gold structures were coated with a 630-nm thick tetraethylorthosilicate layer to achieve higher coupling efficiency for plasmonic gratings using lensed optical probes. We experimentally demonstrated gold input/output plasmonic gratings with an efficiency of about – 3.8 ± 0.2 dB per grating. The measured loss of the plasmonic mode propagating over the surface of the gold waveguide was 0.14 ± 0.02 dB / μm. The work was carried out with the aim of studying integrated plasmonic structures for the development of a hybrid photonic-plasmonic integrated technology.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
