Active Ferromagnetic Metasurface with Topologically Protected Spin Texture for Spectral Filters

Electromagnetic metasurfaces modulate a material's response to electromagnetic waves by specifically arranged elements with dimensions below the wavelength. They have opened new fields of research, including flat optics and nanophotonics on a chip. Ferroma ...

Learnable filter-banks for CNN-based audio applications

Nicolas Aspert, Benjamin Ricaud, Helena Peic Tukuljac, Laurent Colbois

We investigate the design of a convolutional layer where kernels are parameterized functions. This layer aims at being the input layer of convolutional neural networks for audio applications or applications involving time-series. The kernels are defined as ...

Prenatal auditory experience and its sequelae

Lukas Vogelsang, Marin Vogelsang

Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we p ...

Silicon photonic microelectromechanical systems add-drop ring resonator in a foundry process

Niels Quack, Hamed Sattari, Alain Yuji Takabayashi

Photonic add-drop filters are crucial components for the implementation of wavelength division multiplexing (WDM) in fiber-optic communication systems. The recent progress in photonic integration has shown the potential to integrate photonic add-drop filte ...

Highly Integrated Multi-Material Fibers for Soft Robotics

Fabien Sorin, Stella Andréa Françoise Laperrousaz, Hritwick Banerjee, Andreas Leber, Chaoqun Dong, Nicola Bartolomei, Bastien Schyrr

Soft robots are envisioned as the next generation of safe biomedical devices in minimally invasive procedures. Yet, the difficulty of processing soft materials currently limits the size, aspect-ratio, manufacturing throughput, as well as, the design comple ...

Ultraviolet Filtration Passivator for Stable High-Efficiency Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Yi Zhang, Bing Zhang, Keith Gregory Brooks

Although the published values of power conversion efficiency (PCE) have increased continuously in recent years for perovskite solar cells (PSCs), improvements in the stability and performance of PSCs with conventional TiO2 or SnO2 electron transport layers ...

Ultra-Compact Ka-band Metamaterial Waveguide Filters, Fabricated by Lost-Wax Casting

Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam

This paper proposes a novel technique for the design of miniaturized Ka-band filters based on locally resonant metamaterials (LRMs), which are fabricated monolithically using lost wax casting. We implement ultra-small metamaterial filters by exploiting a n ...

Towards a N77 Electroacoustic Filter Using Thin Films of Crystalline Y-cut Lithium Niobate

Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky

This paper presents the use of a novel type of resonators made of a thin membrane of Y-cut Lithium Niobate that has an array of interdigitated electrodes on the top, and a floating metal on the bottom. Each electrode gives rise to a quasi-independent reson ...
