Computational study of NEMS diaphragm sensor using triple nano-ring resonator

A nano-opto-mechanical pressure sensor via ring resonator.

This paper reports a nano-opto-mechanical pressure sensor based on nano-scaled ring resonator. The pressure is measured through the output spectrum shift which is induced via mechanical deformation of the ring resonator. The sensitivity as high as 1.47 pm/kPa has been experimentally achieved which agrees with numerical prediction. Due to the strong variation of sensitivity with different ring r...

Wide FSR Triple Ring Resonator

Electrical Transduction of Graphene NEMS Resonator

Graphene, an atomically thin sheet consisting of only one layer of carbon atoms, attracts intensive research interest since its recent discovery [1], not only due to the simple fabrication process and its unique electronic properties, but also because of the ultimate mechanical strength as well [2], especially for nanoelectromechanical system (NEMS) applications. Here we report the preparation ...

Improving the Triple Coupled Ring-Resonator Performance as an Optical Filter

In this paper, a three ring-resonator serially coupled is considered as an optical filter. We are going to improve the performance of the designed optical filter by increasing the quality factor and finesse of filtered wavelengths. The first and last rings are coupled to the bus waveguides that carry the input and output fields. The effect of coupling parameters and ring radii on the filtering ...
