Laser written mirror profiles for open-access fiber Fabry-Pérot microcavities
Jannis Hessenauer, Ksenia Weber, Julia Benedikter +4
We demonstrate laser-written concave hemispherical structures produced on the endfacets of optical fibers that serve as mirror substrates for tunable open-access microcavities. We…
Phyllotaxis-inspired Nanosieves with Multiplexed Orbital Angular Momentum
Zhongwei Jin, David Janoschka, Junhong Deng +15
Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex ge…
80-degree field-of-view transmissive metasurface-based spatial light modulator
Anton V. Baranikov, Shi-Qiang Li, Damien Eschimese +9
Compact, lightweight and high-performance spatial light modulators (SLMs) are crucial for modern optical technologies. The drive for pixel miniaturization, necessary to improve the…
3D printed hybrid refractive/diffractive achromat and apochromat for the visible wavelength range
Michael Schmid, Florian Sterl, Simon Thiele +2
Three-dimensional (3D) direct laser writing is a powerful technology to create nano- and microscopic optical devices. While the design freedom of this technology offers the possibi…
Chiral plasmonics
Mario Hentschel, Martin Schaeferling, Xiaoyang Duan +2
We present a comprehensive overview of chirality and its optical manifestation in plasmonic nanosystems and nanostructures. We discuss top-down fabricated structures that range fro…
Electrically switchable metasurface for beam steering using PEDOT
Juliane Ratzsch, Julian Karst, Jinglin Fu +10
Switchable and active metasurfaces allow for the realization of beam steering, zoomable metalenses, or dynamic holography. To achieve this goal, one has to combine high-performance…
