I’m broadly interested in phenomena emerging in nanoscale systems, with a particular focus on light-matter interactions and how they may be studied by scanning probe techniques. Staff Scientistbrian.ocallahan@pnnl.govPNNL/EMSL. 7(7) 1408-1409 (1968), Petr Křen IDEX (NYSE: IEX) is a company that has undoubtedly touched your life in some way. Tip-enhanced Raman spectroscopy and photoluminescence. But how to improve its resolution? For simultaneous spatial information we explore new routes for ultrahigh resolution optical imaging far beyond the diffraction limit. In the case of the barcode reader, the imaging system consists of several thick lenses and ... Ptychography is a scanning Coherent Diffraction Imaging (CDI) method for reconstructing a complex valued object function from intensity measurements recorded in the Fraunhofer or Fresnel diffraction region. From clamps that hold air bags safely in place, components used in DNA sequencing, to the Hurst Jaws of Life® rescue tools, we make thousands of products that are mission-critical components in everyday activities. formula are insignificant to within a foreseeable precision of Ultrafast laser and grating tip-enhanced near-field optical spectroscopy, imaging of low-dimensional materials and related devices.

Interested in the thermalization of molecular structures, the emergence of dissipative structures in strongly correlated materials, local thermoelectric effects in topological materials, phononic control of quantum phases, caloric effects in ferroic materials, polariton transport in van der Waals-layered materials. Investigates the elementary steps of thermodynamic processes in quantum materials and molecules, by developing thermo-plasmonic nano-imaging and spectroscopy technique with spatio-temporal resolution down to the nanometer-femtosecond scale. sufficiently accurate, procedure for calculating the group refractive Interest in linear and nonlinear optical spectroscopy at surfaces and of nanostructures. Interested in the understanding of photochemical and photocatalyticreactions by ultrafast spectroscopy and ultrafast nano-imaging methods.Also interested in the investigation and coherent control of chemicalreactions and nanostructured materials with phase-shaped laser pulses inthe tip-enhanced strong coupling regime. This is in particular true for focusing of light. Trusted Solutions, Improving Lives ™. 50(35) 6484-6485 (2011). Example: (diode OR solid-state) AND laser [search contains "diode" or "solid-state" and laser], Example: (photons AND downconversion) - pump [search contains both "photons" and "downconversion" but not "pump"]. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored. Here we describe the results of a more rigorous derivation Philip E. Ciddor Postdoctoral fellowroland.wilcken@physik.uni-muenchen.deLMU Munich / FAU Erlangen. For simplicity, it is often assumed that the imaging system consists of a single thin lens. 6(1) 51-59 (1967), L. E. Wood and M. C.

This new source will have an important role within the LINX consortium, where innovative techniques for ... Photonics has been coined as a key enabling technology for the future. Studying charge/energy transfer and imaging optoelectronic properties of many low dimensional materials at nanoscale using correlatedsingle molecule spectroscopy and electrostatic force microscopy (EFM). We develop, manufacture and integrate optics, mechanics and electronics into innovative system solutions. 2.

Two of the Faculty’s spin-out companies (Monica Healthcare and Surepulse) have originated in technology developed by the Optics and Photonics Research Group. Optical fibers are therefore classified as step-index or graded-index, and multimode or single-mode, as illustrated in Fig. Experience with tracking ultrafast Surface Plasmon Polariton pulses in space and time using heterodyne detection technique. The phase of a field is often more important than the amplitude. Infrared s-SNOM on both soft and hard matter materials. Opt. Equations are available to subscribers only. Appl.
