All-Dielectric Nanophotonic via Glass Fluid Instabilities
In this thesis work, we propose to exploit an innovative micro/nano-fabrication process, based on controlled fluid instabilities of a thin viscous film of chalcogenide glass. Amorphous selenium and arsenic triselenide were used in this thesis work, and com ...
EPFL2024Toward Band n78 Shear Bulk Acoustic Resonators Using Crystalline Y-Cut Lithium Niobate Films With Spurious Suppression
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky
This work presents the study of suspended Y-cut Lithium Niobate shear bulk acoustic resonators for wide band filter applications in the frequency range of 3.5-4.5GHz. The resonators consist of a Lithium Niobate film with Aluminum top interdigitated electro ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Study of Thin Film LiNbO3 Laterally Excited Bulk Acoustic Resonators
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Hüseyin Baris Atakan, Victor Plessky
This work presents an in-depth study of simulation and measurement results of laterally excited shear bulk acoustic resonators (XBAR) in Lithium Niobate, at 5 GHz with high electromechanical coupling factor (k(t)(2)) as high as 25%, and with impedances at ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Silicon 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 ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2022Development of an 11-channel multi wavelength imaging diagnostic for divertor plasmas in MAST Upgrade
Basil Duval, Yanis Andrebe, Artur Perek, Wouter Vijvers
Divertor detachment and alternative divertor magnetic geometries are predicted to be promising approaches to handle the power exhaust of future fusion devices. In order to understand the detachment process caused by volumetric losses in alternative diverto ...
AMER INST PHYSICS2021Molecular Basis of CLC Antiporter Inhibition by Fluoride
Ursula Röthlisberger, Simone Meloni, Viacheslav Bolnykh, Thomas Beck, Paolo Carloni
CLC channels and transporters conduct or transport various kinds of anions, with the exception of fluoride, which acts as an effective inhibitor. Here, we performed sub-nanosecond DFT-based QM/MM simulations of the E. coli anion/proton exchanger ClC-ec1 an ...
AMER CHEMICAL SOC2020Cathodoluminescent screen imaging system for seeded blob detection in toroidal plasma experiment
Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Paul Bowen, Marcelo Baquero Ruiz, Carlos Morais, Fabian Manke
We designed and built a diagnostic based on a cathodoluminescent screen for the detection of turbulent plasma structures with high spatial resolution. The screen is coated with a low threshold energy cathodoluminescent powder that emits light when exposed ...
