在受限的几何结构中产生纳米尺度的单个光子是一个令人兴奋的研究领域，旨在利用局部电磁场进行光操纵。将发射器与纳米结构介质相结合的光子系统的突出挑战之一是将由嵌入式源发射的光子选择性地引导到特定的光学模式中，以及在集成系统中的远距离位置处传输光子。在这里，我们表明，软物质纳米纤维，电纺与嵌入式发射器，联合收割机结合亚波长场本地化和大宽带近场耦合与低传播损耗。通过动量谱，我们量化了模式耦合效率，确定了单模耦合的机制。这些纳米纤维不依赖于共振相互作用，使其成为室温操作的理想选择，并为未来的量子信息技术提供了可扩展的平台。
Nanoscale generation of individual photons in confined geometries is an exciting research field aiming at exploiting localized electromagnetic fields for light manipulation. One of the outstanding challenges of photonic systems combining emitters with nanostructured media is the selective channelling of photons emitted by embedded sources into specific optical modes and their transport at distant locations in integrated systems. Here, we show that soft-matter nanofibers, electrospun with embedded emitters, combine subwavelength field localization and large broadband near-field coupling with low propagation losses. By momentum spectroscopy, we quantify the modal coupling efficiency identifying the regime of single-mode coupling. These nanofibers do not rely on resonant interactions, making them ideal for room-temperature operation, and offer a scalable platform for future quantum information technology.
