Competition between electronic Kerr and free carrier effects in an ultimate-fast optically switched semiconductor microcavity
electronic Kerr free carrier effects semiconductor microcavity Optics
2012/5/17
We have performed ultrafast pump-probe experiments on a GaAs-AlAs microcavity with a resonance near 1300 nm in the "original" telecom band. We concentrate on ultimate-fast optical switching of the cav...
Efficient method of designing optically-pumped vertical external cavity surface emitting lasers having equally excited quantum wells
Efficient method optically-pumped vertical external cavity surface emitting lasers equally excited quantum wells Optics
2012/4/20
Even distribution of carriers allows to maximize optical gain of the Optically-Pumped Vertical External Cavity Surface Emitting Laser. In this paper we show how to distribute the quantum wells and blo...
Depth Profile of Optically Recorded Patterns in Light-Sensitive Liquid Crystal Elastomers
Depth Profile Optically Recorded Patterns Light-Sensitive Liquid Crystal Elastomers
2011/8/11
Abstract: We investigated nonlinear absorption and photobleaching processes in a liquid crystal elastomer (LCE) doped with light-sensitive azobenzene moiety. A conventional one-dimensional holographic...
Surface optomechanics: Calculating optically excited acoustical whispering gallery modes in microspheres
optomechanics Calculating optically microspheres
2011/9/5
Stimulated Brillouin scattering recently allowed experimental excitation of surface acoustic resonances in micro-devices, enabling vibration at rates in the range of 50 MHz to 12 GHz. The experimental...
Optically induced spin polarisation of the NV- centre in diamond: role of electron-vibration interaction
Optically induced spin polarisation NV- centre in diamond: role electron-vibration interaction
2010/11/22
The novel aspect of the centre (NV−) in diamond is the high degree of spin polarisation achieved through optical illumination. In this paper it is shown that the spin polarisation occurs as a co...
Amplified Stimulated Terahertz Emission at Room temperature from Optically Pumped Graphene
Terahertz Emission Room temperature Optically Pumped Graphene
2010/11/17
Room temperature Terahertz stimulated emission and population inversion in optically pumped graphene is reported. We experimentally observe fast relaxation and relatively slow recombination dynamics ...
Optically Levitating Dielectrics in the Quantum Regime: Theory and Protocols
Optically Levitating Dielectrics Quantum Regime Theory Protocols
2010/11/5
We provide a general quantum theory to describe the coupling of light with the motion of a dielectric object inside a high finesse optical cavity. In particular, we derive the total Hamiltonian of the...
Entangling unstable optically active matter qubits
Entangling unstable optically active matter qubits
2010/10/20
In distributed quantum computation, small devices composed of a single or a few qubits are networker together to achieve a scalable machine. Typically there is an optically active matter qubit at each...
Optically detected NMR of optically hyperpolarized 31P neutral donors in 28Si
Optically optically 31P neutral donors
2010/10/27
The electron and nuclear spins of the shallow donor 31P are promising qubit candidates invoked in many proposed Si-based quantum computing schemes. We have recently shown that the near-elimination of ...
A study on the real-time radiation dosimetry measurement system based on optically stimulated luminescence
optically stimulated luminescence online and realtime dosimeter
2009/8/17
The optically stimulated luminescent (OSL) radiation dosimeter technically surveys a wide dynamic measurement range and a high sensitivity. Optical fiber dosimeters provide capability for remote monit...
