The Presence of Ultralow Densities of Nanocrystallites in Amorphous Poly(lactic acid) Microspheres

Ultralow densities of crystalline nanospheres have been detected in amorphous polymer microspheres by utilizing the unique sensitivity of second-order nonlinear optical techniques to anisotropy. Vibrational sum frequency scattering (SFS) and X-ray diffract ...

High-impedance frequency-agile THz dipole antennas using graphene

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

The concept and analysis of a THz frequency-reconfigurable antennas using graphene are presented. The antennas exploit dipole-like plasmonic resonances that can be frequency-tuned on large range via the electric field effect in a graphene stack. In additio ...

Light confinement effect of non-spherical nanoscale solid immersion lenses

Hans Peter Herzig, Gaël David Osowiecki, Toralf Scharf, Myun Sik Kim, David Nguyen

We report on the light confinement effect observed in non-ideally shaped (i.e., non-spherical) nanoscale solid immersion lenses (SILs). To investigate this effect, nanostructures of various shapes are fabricated by electron-beam lithography. When completel ...

Electro and pressure tunable cholesteric liquid crystal devices based on ion-implanted flexible substrates

Herbert Shea, Andreas Vasdekis, Muhamed Niklaus, Jae-Woo Choi, Luc Maffli, Luciano De Sio

We report an electro-responsive and pressure sensitive device based on conductive polydimethylsiloxane (PDMS) combined with a short pitch Cholesteric Liquid Crystal (CLC). Ion-implantation and surface chemistry in PDMS enable both the induction of conducti ...

Optofluidic Microstructures Containing Liquid Crystals

Andreas Vasdekis, Luciano De Sio, Marilisa Romito

We report our recent efforts on the realization and characterization of a conductive polydimethylsiloxane (PDMS) microstructure containing liquid crystals (LC). The sample has been realized by means of a layer by layer strategy. An indium tin oxide (ITO) l ...

The varying w spread spectrum effect for radio interferometric imaging

Yves Wiaux, Rafael Eduardo Carrillo Rangel, Jason Douglas McEwen

We study the impact of the spread spectrum effect in radio interferometry on the quality of image reconstruction. This spread spectrum effect will be induced by the wide ﬁeld-of-view of forthcoming radio interferometric telescopes. The resulting chirp modu ...

Ferroelectric control of magnetic domains in ultra-thin cobalt layers

Nava Setter, Igor Stolichnov, Zhouji Huang

Non-volatile ferroelectric control of magnetic domains has been demonstrated in ultra-thin cobalt layers at room temperature. The sensitivity of magnetic anisotropy energy to the electronic structure in a few atomic layers adjacent to the interface allows ...

Electric field effect in graphite crystallites

Klaus Kern, Marko Burghard, Kannan Balasubramanian, Adarsh Singh Sagar

Graphite is a highly anisotropic crystal with a quasi-two-dimensional electronic structure exhibiting high intrinsic charge carrier mobility. Here, we investigate the effect of an electric field on the resistance of individual graphite crystallites with a ...

Fabrication of Bragg Gratings in Microstructured Bi:SiO2 Optical Fiber Using an ArF Laser

Hans Georg Limberger, Georgios Violakis

An ArF excimer laser was used to fabricate Bragg gratings in Bi:SiO2 core - microstructured cladding optical fiber. Average and modulated refractive index changes of 2.7 × 10E-4 and 1.0 × 10E-4 were induced in pristine fiber. Fiber luminescence was also me ...
