Transparent polycrystalline alumina using spark plasma sintering: Effect of Mg, Y and La doping

Paul Bowen, Michael Stuer, Ulrich Aschauer, Zhe Zhao

Transparent polycrystalline alumina (PCA) is a promising replacement for sapphire. Its optical properties however are highly dependent on the grain size and residual porosity which need to be controlled for real inline transmittances (RIT), that are high e ...

Fabry-Perot Nanocavities in 3D Plasmonic Crystals for Enhanced Biosensing

Hatice Altug

Extraordinary light transmission effect through Fabry-Perot cavities in 3D plasmonic cystals consisting of two physically separated metallic nanohole and nanodisk array layers is demonstrated. These cavity resonances are highly sensitive to refractive inde ...

Retardation-induced plasmonic blinking in coupled nanoparticles

Olivier Martin, Holger Fischer

We study how retardation leads to interference effects in radiatively coupled plasmonic nanoparticles. We show that inclined illumination through a glass substrate on two plasmonic particles results in either an enhanced field or an attenuated field locali ...

Hybridized nanocavities as single-polarized plasmonic antennas

Hatice Altug, Shyamsunder Erramilli

We experimentally demonstrate that hybridized nanocavities in optically thick metal films radiate in coherence, and act as an efficient single-polarized plasmonic nano-antenna array. We employ propagating and localized plasmons to enhance polarization cont ...

Polarization-sensitive near-field investigation of photonic crystal microcavities

Laurent Balet, Massimo Gurioli

We report on polarization sensitive imaging of two-dimensional photonic crystal microcavity modes. By using a near-field scanning optical microscope with a polarization sensitive setup, it is possible to selectively map, with a resolution beyond the diffra ...

Surface Excitation of Hybridized Plasmons In Metallic Nanocavities

Hatice Altug

We experimentally demonstrate surface excitation of hybridized plasmons in metallic nanocavities. We developed a quasi-static model connecting this observation to plasmonic antenna behavior for extraordinary light transmission effect. ...

Localized Plasmonic Control of Extraordinary Light Tranmission in Rectangular Coaxial Aperture Arrays at Mid-IR

Hatice Altug, Shyamsunder Erramilli, Xiaoyan Wang

It has been theoretically predicted and experimentally shown that circular coaxial aperture arrays have higher transmissivities with respect to simple circular ones. This observation is mainly attributed to the propagating waveguide modes supported by the ...

A semiclassical approach for electro-optic effect

Ahmad Ajdar Zadeh Oskouei

In this article, we present a semiclassical approach for modeling of electro-optic (EO) effect. We calculate phase retardation between x and y polarizations of optical electric field when a transverse external electric field is applied. Our results are wel ...

Automatic procedure for aberrations compensation in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Nicolas Aspert, Pierre Marquet, Jonas Kühn, Florian Charrière, Mihaela Marian

Digital Holographic Microscopy (DHM) is a powerful imaging technique allowing, from a single amplitude image (amplitude and phase), reflected acquisition (hologram), the reconstruction of the entire complex wave front by or transmitted through an object. B ...

Spectral reflection and dot surface prediction models for color halftone prints

Roger Hersch, Patrick Emmel, Frédérique Crété

The proposed new spectral reflection model enhances the classical Clapper-Yule model by taking into account the fact that proportionally more incident light through a given colorant surface is reflected back onto the same colorant surface than onto other c ...
