Nanobeam photonic crystal cavity quantum dot laser

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. We study the cavity lasers under both 780 nm and 980 nm pump, finding thresholds as low as 0.3 uW and 19 uW

A nonlocal elasticity theory to model the static behaviour of edge-cracked nanobeams

Fracture and Structural Integrity
In the present paper, the mechanical behaviour of edge-cracked nanobeams under Mixed-Mode loading is analytically investigated by means of the Stress-Driven nonlocal model. Firstly, the proposed formulation is outlined, and then applied to the case of a

Static Bending Analysis of Nanobeam-Substrate Medium Systems Incorporating Mixture Stress-Driven Nonlocality, Surface Energy, and Substrate-Structure Interactions [PDF]

Journal of Applied and Computational Mechanics
This paper proposes a novel nonlocal beam-substrate model for the static bending analysis of a nanobeam system on a substrate medium. The proposed model incorporates the coupling interaction among nonlocality, surface energy, and substrate-structure ...

Single and Coupled Nanobeam Cavities

, 2013
In the coming decade in physics great effort will probably be devoted, among other things, to improving quantum storage and the development of quantum computer. To make use of quantum processes one should avoid decoherence influence of surroundings, or use specifically designed environment to modify the process considered. This is the case when an atom
