Optical slot waveguides fabricated on the silicon-on-insulator (SOI) platform enables direct light–matter interaction [1]. Its ring resonators are promising for trace-gas sensing [2], microparticle trapping [3], and nano-optomechanical mass and displacement measurements [4]. To date, slot ring/racetrack structures on buried oxide (BOX) have been adopted in the above applications. However, their...

We present the fabrication of parylene-based hollow nanomechanical resonators, following a simple two step fabrication process with a thermal budget of less than 120°C. This process is ideal for fast prototyping and compatible with most materials used in microand nano-fabrication. In particular, the example we present here shows a hybrid structure with silicon nitride and parylene, but we have ...

In this paper, free vibration analysis of a polymer-based nano-composite beam reinforced by boron-nitride nanotubes and subjected on elastic foundation, is studied. Smooth and defect-free nanotubes with uniform and directly- orientated in matrix are intended. Also, nanotubes’ distribution in the thickness direction of beam is regarded as a uniform distribution of the three different targeted on...

Decomposition of chromophore molecules under direct electron beam irradiation reduces the refractive index of chromophore containing polymers. The induced refractive index contrast between the exposed and unexposed regions is high enough for waveguide bends of small radius and thus micro-ring resonator devices. This electron beam bleaching of chromophore-containing polymers provides a fabricati...

In this paper, the transverse vibration of cracked nano-beam has been studied based on modified couple stress theory. Crack is modeled by a rotational spring that creates a discontinuity. Frequency equations of cracked nano-beam with some typical boundary conditions are derived and the frequency parameter for different crack positions, crack parameter and length scale parameters value are calcu...

Graphene has proven to be a promising conductive layer in fabricating optical plasmon resonators on insulator substrate using electron beam lithography and has the potential to construct electrically controlled active plasmon resonators. In this study, we investigate the effect of graphene on plasmon resonance using graphene and Au plasmon resonator system as a model at visible and near-infrare...

We report on direct measurements of the magnetic near-field of metamaterial split ring resonators at terahertz frequencies using a magnetic field sensitive material. Specifically, planar split ring resonators are fabricated on a single magneto-optically active terbium gallium garnet crystal. Normally incident terahertz radiation couples to the resonator inducing a magnetic dipole oscillating pe...

Mechanical resonators based on low-dimensional materials provide a unique platform for exploring a broad range of physical phenomena. The mechanical vibrational states are indeed extremely sensitive to charges, spins, photons, and adsorbed masses. However, the roadblock is often the readout of the resonator, because the detection of the vibrational states becomes increasingly difficult for smal...

We have used optical drive and detection to study dissipation in silicon nitride beam resonators. We are able to tune resonant frequency as well as quality factor in a given nanostring resonator by several hundred percent by tuning the stress in real time, providing a unique look into the sources of dissipation for this class of nanoresonator. A record room temperature quality factor of 390,000...
