Ultra low quantum decoherence nano-optomechanical systems

Mohammadjafar Bereyhi

Thermal motion of a room-temperature mechanical resonator typically dominates the quantum backaction of its position measurement. This is a longstanding barrier for exploring cavity optomechanics at room temperature. In order to enter the quantum regime of ...

Subwavelength Metawaveguide Filters and Metaports

Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam

This paper proposes an alternative technique for the design of miniaturized waveguide filters based on locally resonant metamaterials (LRMs). We implement ultrasmall metamaterial filters (metafilters) by exploiting a subwavelength (sub-λ) guiding mechanism ...

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 ...

FEM simulation: Thermal properties of thin film quartz and silicon resonators

This semester project aimed at simulating two approaches for low temperature dependence of resonance frequency of resonators. The first one consists in using AT-cut quartz as the resonator’s material. The AT-cut quartz wafers are made using a 35° angle wit ...

Collective dynamics in nonlinear resonators coupled in spatial and synthetic dimensions

Tobias Kippenberg, Aleksandr Tusnin, Alexey Tikan

We theoretically investigate chaotic and stable structures in coupled-resonator chains and synthetic frequency dimension influenced by Kerr nonlinearity, thereby bringing insights in the emerging field of soliton generation in chains and lattices of high-Q ...

Balancing of Coupled Piezoelectric NEMS Resonators

Luis Guillermo Villanueva Torrijo, Damien Maillard, Johannes Mathis Valentin Lemonde

Micro and Nano Electro Mechanical systems (M/NEMS) have a lot of potential to be used for sensing in different schemes and operation modes. We focus here on the use of coupled resonators for sensing and address the major limitation that these systems face, ...
