Subnatural linewidth single photons from a quantum dot.

Physical review letters

Matthiesen C, Vamivakas AN, Atatüre M.
PMID: 22463634
Phys Rev Lett. 2012 Mar 02;108(9):093602. doi: 10.1103/PhysRevLett.108.093602. Epub 2012 Feb 28.

The observation of quantum-dot resonance fluorescence enabled a new solid-state approach to generating single photons with a bandwidth approaching the natural linewidth of a quantum-dot transition. Here, we operate in the small Rabi frequency limit of resonance fluorescence--the Heitler...

High Resolution Synchrotron X-Radiation Diffraction Imaging of Crystals Grown in Microgravity and Closely Related Terrestrial Crystals.

Journal of research of the National Institute of Standards and Technology

Steiner B, Dobbyn RC, Black D, Burdette H, Kuriyama M, Spal R, van den Berg L, Fripp A, Simchick R, Lal RB, Batra A, Matthiesen D, Ditchek B.
PMID: 28184117
J Res Natl Inst Stand Technol. 1991 May-Jun;96(3):305-331. doi: 10.6028/jres.096.017.

Irregularities in three crystals grown in space and in four terrestrial crystals grown under otherwise comparable conditions have been observed in high resolution diffraction imaging. The images provide important new clues to the nature and origins of irregularities in...

Millimeter-wave compressive holography.

Applied optics

Cull CF, Wikner DA, Mait JN, Mattheiss M, Brady DJ.
PMID: 20648123
Appl Opt. 2010 Jul 01;49(19):E67-82. doi: 10.1364/AO.49.000E67.

We describe an active millimeter-wave holographic imaging system that uses compressive measurements for three-dimensional (3D) tomographic object estimation. Our system records a two-dimensional (2D) digitized Gabor hologram by translating a single pixel incoherent receiver. Two approaches for compressive measurement...

Observation of spin-dependent quantum jumps via quantum dot resonance fluorescence.

Nature

Vamivakas AN, Lu CY, Matthiesen C, Zhao Y, Fält S, Badolato A, Atatüre M.
PMID: 20844531
Nature. 2010 Sep 16;467(7313):297-300. doi: 10.1038/nature09359.

Reliable preparation, manipulation and measurement protocols are necessary to exploit a physical system as a quantum bit. Spins in optically active quantum dots offer one potential realization and recent demonstrations have shown high-fidelity preparation and ultrafast coherent manipulation. The...

Strategies to Identify Recognition Signals and Targets of SUMOylation.

Biochemistry research international

Da Silva-Ferrada E, Lopitz-Otsoa F, Lang V, Rodríguez MS, Matthiesen R.
PMID: 22811915
Biochem Res Int. 2012;2012:875148. doi: 10.1155/2012/875148. Epub 2012 Jul 01.

SUMOylation contributes to the regulation of many essential cellular factors. Diverse techniques have been used to explore the functional consequences of protein SUMOylation. Most approaches consider the identification of sequences on substrates, adaptors, or receptors regulating the SUMO conjugation,...

Observation of all the intermediate steps of a chemical reaction on an oxide surface by scanning tunneling microscopy.

ACS nano

Matthiesen J, Wendt S, Hansen JØ, Madsen GK, Lira E, Galliker P, Vestergaard EK, Schaub R, Laegsgaard E, Hammer B, Besenbacher F.
PMID: 19309169
ACS Nano. 2009 Mar 24;3(3):517-26. doi: 10.1021/nn8008245.

By means of high-resolution scanning tunneling microscopy (STM), we have revealed unprecedented details about the intermediate steps for a surface-catalyzed reaction. Specifically, we studied the oxidation of H adatoms by O(2) molecules on the rutile TiO(2)(110) surface. O(2) adsorbs...

Electro-optic light modulation and THz generation in locally plasma-activated silicon nanophotonic devices.

Optics express

Matheisen C, Waldow M, Chmielak B, Sawallich S, Wahlbrink T, Bolten J, Nagel M, Kurz H.
PMID: 24663865
Opt Express. 2014 Mar 10;22(5):5252-9. doi: 10.1364/OE.22.005252.

Silicon is not an electro-optic material by itself but the required second-order optical nonlinearity can be induced by breaking the inversion symmetry of the crystal lattice. Recently, an attractive approach has been demonstrated based on a surface-activation in a...

Investigation of local strain distribution and linear electro-optic effect in strained silicon waveguides.

Optics express

Chmielak B, Matheisen C, Ripperda C, Bolten J, Wahlbrink T, Waldow M, Kurz H.
PMID: 24150373
Opt Express. 2013 Oct 21;21(21):25324-32. doi: 10.1364/OE.21.025324.

We present detailed investigations of the local strain distribution and the induced second-order optical nonlinearity within strained silicon waveguides cladded with a Si₃N₄ strain layer. Micro-Raman Spectroscopy mappings and electro-optic characterization of waveguides with varying width w(WG) show that...
