Self-Assembly of Lipid-Biopolymer Periodic Nanostructures on Photonic Length Scales
Rushna Quddus, Meron Debas, Stefan Salentinig +2
The self-assembly of photonic nanostructures in insects involves chitin, proteins, and lipids. While synthetic photonic systems have been extensively studied, current lipid-based s…
Minireview on Disordered Optical Metasurfaces
P. Lalanne, A. Dmitriev, C. Rockstuhl +2
The use of coherent wave phenomena to enhance device performance is a cornerstone of modern optics. In juxtaposition to (locally) periodic metasurfaces, their disordered counterpar…
Large-Scale Bottom-Up Fabricated 3D Nonlinear Photonic Crystals
Viola Valentina Vogler-Neuling, Ülle-Linda Talts, Rebecca Ferraro +9
Nonlinear optical effects are used to generate coherent light at wavelengths difficult to reach with lasers. Materials periodically poled or nanostructured in the nonlinear suscept…
Second-harmonic generation tuning by stretching arrays of GaAs nanowires
Grégoire Saerens, Esther Bloch, Kristina Frizyuk +7
We present a wearable device with III-V nanowires in a flexible polymer, which is used for active mechanical tuning of the second-harmonic generation intensity. An array of vertica…
Enhanced electro-optic modulation in resonant metasurfaces of lithium niobate
Helena Weigand, Viola V. Vogler-Neuling, Marc Reig Escalé +5
In display technologies or data processing, planar and subwavelength free-space components suited for flat photonic devices are needed. Metasurfaces, which shape the optical wavefr…
