Sub-cycle optical control of current in a semiconductor: from the multiphoton to the tunneling regime
Tim Paasch-Colberg, Stanislav Yu. Kruchinin, Özge Sağlam +10
Nonlinear interactions between ultrashort optical waveforms and solids can be used to induce and steer electric current on a femtosecond (fs) timescale, holding promise for electro…
High refractive index Fresnel lens on a fiber fabricated by nanoimprint lithography for immersion applications
Alexander Koshelev, Giuseppe Calafiore, Carlos Piña-Hernandez +7
In this Letter we present a Fresnel lens fabricated on the end of an optical fiber. The lens is fabricated using nanoimprint lithography of a functional high refractive index mater…
Nanoimprint of a 3D structure on an optical fiber for light wavefront manipulation
Giuseppe Calafiore, Alexander Koshelev, Frances I. Allen +6
Integration of complex photonic structures onto optical fiber facets enables powerful platforms with unprecedented optical functionalities. Conventional nanofabrication technologie…
