TL;DR: The fabrication of a three-dimensional structure achieved by direct nanoimprint lithography on the facet of an optical fiber should enable advancements in areas such as integrated optics and sensing, achieving enhanced portability and versatility of fiber optic components.

TL;DR: The main advantage of the presented Fresnel lens compared to a conventional fiber lens is its high refractive index, which enables efficient light focusing even inside other media, such as water or an adhesive.

TL;DR: This novel nano-fabrication approach promises a low-cost, high-throughput, and reproducible manufacturing of advanced nano-optical devices, and enables sub-diffraction limited imaging with a spatial resolution consistent with the gap size.

TL;DR: In this article, a technique based on anisotropic etching of silicon was proposed to produce very small angle facets with a high degree of perfection, typically less than 1°.

TL;DR: In this article, a 3D beam splitter has been designed, imprinted and optically characterized using direct nano-print lithography on the facet of an optical fiber, which can achieve high accuracy and coaxial alignment of the optical device with respect to the fiber core.
