Special Issue Information

Dear Colleagues,

In the last decades Micro/Nano-resonators have emerged as excellent tools for sensing. Their applications cover a large range of fields going from the detection of extremelly tiny forces to clinical diagnosis. As the size of the devices has been minituarized, researchers have improved considerably their sensititity. Regarding biosensing, Micro/Nano-resonators have been used to detect and weigth single cells, viruses and even proteins, which finds enormous applications not only in clinical dianosis but also in biomedicine.

This Special Issue aims to gather the Micro/Nano-resonator sensing community and emphasize the relevance of this field in plenty of diverse scientific areas. We invite manuscripts for this forthcoming Special Issue on all aspects regarding the application and implementation of these devices, such as advances in fabrication, design and modeling, novel approaches and applications, etc. Both experimental and theoretical contributions are welcome.

We look forward to and welcome your participation in this Special Issue. Topics include but are not limited to:

Biological and chemical sensing
Clinical diagnosis
Environmental analysis and air quality control
Force and quantum sensing
Optomechanical sensing
Thermometry and Humidity sensing
Fluid applications
Design and fabrication of novel platforms
Novel theoretical models

We theoretically investigate the optical output fields of a photonic-molecule optomechanical system in an optomechanically induced transparency (OMIT) regime, in which the optomechanical cavity is optically driven by a strong pump laser field and a weak probe laser field and the mechanical mode is driven by weak coherent phonon driving. The numerical simulations indicate that when the driven frequency of the phonon pump equals the frequency difference of the two laser fields, we show an enhancement OMIT where the probe transmission can exceed unity via controlling the driving amplitude and pump phase of the phonon driving. In addition, the phase dispersion of the transmitted probe field can be modified for different parametric regimes, which leads to a tunable delayed probe light transmission. We further study the group delay of the output probe field with numerical simulations, which can reach a tunable conversion from slow to fast light with the manipulation of the pump laser power, the ratio parameter of the two cavities, and the driving amplitude and phase of the weak phonon pump.

Overhang provides a simple but effective way of coupling (sub)structures, which has been widely adopted in the applications of optomechanics, electromechanics, mass sensing resonators, etc. Despite its simplicity, an overhanging structure demonstrates rich and complex dynamics such as mode splitting, localization and eigenfrequency veering. When an eigenfrequency veering occurs, two eigenfrequencies are very close to each other, and the error associated with the numerical discretization procedure can lead to wrong and unphysical computational results. A method of computing the eigenfrequency of two overhanging beams, which involves no numerical discretization procedure, is analytically derived. Based on the method, the mode localization and eigenfrequency veering of the overhanging beams are systematically studied and their variation patterns are summarized. The effects of the overhang geometry and beam mechanical properties on the eigenfrequency veering are also identified. Full article

The emergence of graphene and other two-dimensional materials overcomes the limitation in the characteristic size of silicon-based micro-resonators and paved the way in the realization of nano-mechanical resonators. In this paper, we review the progress to date of the research on the fabrication methods, resonant performance, and device applications of graphene-based nano-mechanical resonators, from theoretical simulation to experimental results, and summarize both the excitation and detection schemes of graphene resonators. In recent years, the applications of graphene resonators such as mass sensors, pressure sensors, and accelerometers gradually moved from theory to experiment, which are specially introduced in this review. To date, the resonance performance of graphene-based nano-mechanical resonators is widely studied by theoretical approaches, while the corresponding experiments are still in the preliminary stage. However, with the continuous progress of the device fabrication and detection technique, and with the improvement of the theoretical model, suspended graphene membranes will widen the potential for ultralow-loss and high-sensitivity mechanical resonators in the near future.
