Nanoimprint of a 3D structure on an optical fiber for light wavefront manipulation
Giuseppe Carlo Calafiore,Alexander Koshelev,Frances I. Allen,Frances I. Allen,Scott Dhuey,Simone Sassolini,Ed Wong,Paul Lum,Keiko Munechika,Stefano Cabrini +9 more
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.
Journal ArticleDOI
High refractive index Fresnel lens on a fiber fabricated by nanoimprint lithography for immersion applications
Alexander Koshelev,Giuseppe Carlo Calafiore,Carlos Pina-Hernandez,Frances I. Allen,Scott Dhuey,Simone Sassolini,Ed Wong,Paul Lum,Keiko Munechika,Stefano Cabrini +9 more
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: In this paper, the authors presented a Fresnel lens fabricated on the end of an optical fiber, which is suitable for mass production and showed a near diffraction limited focal spot of 810 nm in diameter at the 1/e2 intensity level for a wavelength of 660 nm.
Journal ArticleDOI
Use of Ultrananocrystalline Diamond as a Phase-contrast Aperture Material
TL;DR: Boron-doped "ultrananocrystalline diamond" (UNCD) is investigated as a potential material for making devices that can be placed in the back focal plane of the objective lens of a TEM, the goal being to produce high contrast for in-focus images of weak phase objects as discussed by the authors.
