We report a Silicon nano-opto-mechanical device in which a nanomechanical doubly-clamped beam resonator is integrated to an optical microdisk cavity. Small flexural oscillations of the beam cause intensity modulations in the circulating optical field in the nearby microdisk cavity. By monitoring the corresponding fluctuations in the cavity transmission via a fiber-taper, one can detect these os...

Magnetic-field-resilient superconducting coplanar waveguide (SCPW) resonators are essential for developing integrated quantum circuits. Molybdenum–Rhenium (MoRe), which is a disordered alloy forming highly transparent contact to the graphene and carbon nanotubes, would be promising platform realizing field-resilient SCPW combined with nano-hybrid devices. We fabricated MoRe investigated their m...

In semiconductor nano-optomechanical resonators, several forms of light-matter interaction can enrich the canonical radiation pressure coupling light and mechanical motion give rise to new dynamical regimes. Here, we observe an electro-optomechanical modulation instability in a gallium arsenide disk resonator. The regime is evidenced by concomitant formation regular dense combs radio-frequency ...

We study the dynamics of a resonantly driven nonlinear resonator (primary) that is nonlinearly coupled to non-resonantly linear (secondary) with relatively short decay time. Due its relaxation time, secondary adiabatically tracks primary and modifies response. Our model, which motivated by experimental studies on interaction between nano- micro-resonators, simple can be analyzed analytically nu...

This paper proposes a novel nano-sized refractive index sensor based on the Fano resonance phenomenon. The main structure consists of two short tubes metal-insulation-metal waveguide and an internal Z-ring resonator. authors used finite element approach to analyze nanoscale sensing performance system. Simulation results show that asymmetries in geometry will lead splitting. explicitly explores ...

This research quantitatively investigates fluid damping of MEMS and NEMS flexural resonators such as scanning probe and carbon nano-tube resonators, aiming to improve the quality factor prediction and therefore the resonator design. Fluid damping in beam-type resonators is most affected by resonant frequency, device dimensions and cross-sectional shape which are systematically examined within. ...

Rigorous simulations of bent and branched sections of coupled resonator optical waveguides (CROWs) composed of side-coupled whispering gallery (WG) mode microdisks are performed. Pre- and post-fabrication tuning capability of the designed structures is explored, and a novel concept of realization of tunable CROW-based routers and switches is introduced. The proposed tuning mechanism exploits th...

A suspended, doubly clamped single wall carbon nanotube is characterized as driven nano-electromechanical resonator at cryogenic temperatures. Electronically, the carbon nanotube displays small bandgap behaviour with Coulomb blockade oscillations in electron conduction and transparent contacts in hole conduction. We observe the driven mechanical resonance in dc-transport, including multiple hig...
