Nanobeam photonic crystal cavity quantum dot laser [PDF]

Optics Express, 2010
The lasing behavior of one dimensional GaAs nanobeam cavities with embedded InAs quantum dots is studied at room temperature. Lasing is observed throughout the quantum dot PL spectrum, and the wavelength dependence of the threshold is calculated.

Isomerization dynamics of a buckled nanobeam [PDF]

Physical Review E, 2012
We analyze the dynamics of a model of a nanobeam under compression. The model is a two mode truncation of the Euler-Bernoulli beam equation subject to compressive stress.

High Quality factor photonic crystal nanobeam cavities [PDF]

Applied Physics Letters, 2009
We investigate the design, fabrication and experimental characterization of high Quality factor photonic crystal nanobeam cavities in silicon. Using a five-hole tapered 1D photonic crystal mirror and precise control of the cavity length, we designed ...

Thermal Properties of Nanocrystalline Silicon Nanobeams [PDF]

Advanced Functional Materials, 2021
AbstractControlling thermal energy transfer at the nanoscale and thermal properties has become critically important in many applications since it often limits device performance. In this study, the effects on thermal conductivity arising from the nanoscale structure of free‐standing nanocrystalline silicon films and the increasing surface‐to‐volume ...

Operating Nanobeams in a Quantum Fluid [PDF]

Scientific Reports, 2017
AbstractMicroelectromechanical (MEMS) and nanoelectromechanical systems (NEMS) are ideal candidates for exploring quantum fluids, since they can be manufactured reproducibly, cover the frequency range from hundreds of kilohertz up to gigahertz and usually have very low power dissipation. Their small size offers the possibility of probing the superfluid

Single-Crystal Diamond Nanobeam Waveguide Optomechanics [PDF]

Physical Review X, 2015
Optomechanical devices sensitively transduce and actuate motion of nanomechanical structures using light. Single--crystal diamond promises to improve the performance of optomechanical devices, while also providing opportunities to interface nanomechanics with diamond color center spins and related quantum technologies.

The vibration of a nanobeam subjected to constant magnetic field and ramp-type heat under non-Fourier heat conduction law based on the Lord-Shulman model

Advances in Mechanical Engineering, 2023
In this work, the usual Euler–Bernoulli nanobeam has been modeled in the context of the Lord-Shulman thermoelastic theorem which contains the non-Fourier heat conduction law.

Photonic crystal nanobeam lasers [PDF]

Conference on Lasers and Electro-Optics 2010, 2010
Photonic crystal lasers operating at room temperature based on high Q/V nanobeam cavities have been demonstrated. We reported a large spontaneous emission factor (β∼0.97) by fitting the L-L curve with the rate equations.

Vibration and Buckling Analysis of Functionally Graded Flexoelectric Smart Beam [PDF]

Journal of Applied and Computational Mechanics, 2019
In this paper, the buckling and vibration behaviour of functionally graded flexoelectric nanobeam is examined. The vibration and buckling formulations of functionally graded nanobeam are developed by using a new theory that’s presented exclusively for ...

Characterization of 1D photonic crystal nanobeam cavities using curved microfiber [PDF]

, 2010
We investigate high-Q, small mode volume photonic crystal nanobeam cavities using a curved, tapered optical microfiber loop. The strength of the coupling between the cavity and the microfiber loop is shown to depend on the contact position on the ...
