To date, magnetic and negative-index metamaterials at optical frequencies were realized on bulk substrates in the form of thin films with thicknesses on the order of, or less than, optical wavelengths. In this work, we design and experimentally demonstrate, for the first time, fiber-coupled magnetic metamaterials integrated on the transverse cross-section of an optical fiber. Such fiber-metamaterials integration may provide fundamentally new solutions for photonic-on-a-chip systems for sensing, subwavelength imaging, image processing, and biomedical applications.
迄今为止，光频下的磁性和负折射率超材料是以薄膜形式在块状衬底上实现的，其厚度约为光波长量级或小于光波长。在这项工作中，我们首次设计并通过实验证明了集成在光纤横向横截面上的光纤耦合磁性超材料。这种光纤与超材料的集成可为用于传感、亚波长成像、图像处理和生物医学应用的片上光子系统提供全新的解决方案。
