A semiclassical approach for electro-optic effect

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 ...

Enhanced backscattering by multiple nanocylinders illuminated by TE plane wave

Juan Ramon Mosig, Olivier Martin

In this paper, we study the multiple scattering by electrically small (the radius of the cylinder is much smaller than the wavelength) plasmonic nanocylinders near surface plasmon resonance. The cylinders are assumed to be identical in dimension and compos ...

Real-Time Birefringence Measurement with Digital Holographic Microscopy

Christian Depeursinge, Yves Bellouard, Tristan Colomb, Jonas Kühn, Florian Charrière

Digital holographic microscopes using two orthogonal polarized reference waves provides real-time polariscopes. Birefringence induced by internal stress is imaged in optical fibers and in fused silica substrates, where lines are written with low-energy fem ...

Numerical aberrations compensation and polarization imaging in digital holographic microscopy

Tristan Colomb

In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...

Polarization digital holographic microscope: A single acquisition for a complete determination of polarization state

Christian Depeursinge, Tristan Colomb, Etienne Cuche

In this paper, we present a transmission polarization digital holographic microscope (Pol-DHM) that allows for imaging the state of polarization of a wave front with the acquisition of a single hologram. This apparatus records, using a CCD camera, the inte ...

Room-temperature polariton luminescence from a bulk GaN microcavity

Nicolas Grandjean, Jean-François Carlin, Marc Ilegems, Raphaël Butté, Eric Feltin, Gabriel Christmann, Mauro Mosca

We report strong exciton-photon coupling at room temperature in a hybrid high quality bulk 3 lambda/2 GaN cavity with a bottom lattice-matched AlInN/AlGaN distributed Bragg reflector through angle-resolved polarized photoluminescence (PL). Coupling of the ...

Polarization microscopy by use of digital holography: application to optical- fiber birefringence measurements

René Salathé, Christian Depeursinge, Tristan Colomb, Etienne Cuche, Hans Georg Limberger, Pierre Marquet, Florian Dürr

We present a digital holographic microscope that permits one to image polarization state. This technique results from the coupling of digital holographic microscopy and polarization digital holography. The interference between two orthogonally polarized re ...

Birefringence measurement by use of digital holographic microscopy: examples with fiber optics and concrete samples

Christian Depeursinge, Tristan Colomb, Etienne Cuche

In this paper, we present a modified transmission digital holographic microscope that can be used to image the state of polarization. The resulting device, called polarization digital holographic microscope (Pol-DHM), records in off-axis geometry the inter ...

Two-dimensional coupled photonic crystal resonator arrays

Hatice Altug

We present the design and fabrication of photonic crystal structures exhibiting electromagnetic bands that are flattened in all crystal directions, i.e., whose frequency variation with a wave vector is minimized. Such bands can be used to reduce group velo ...

Jones vector imaging by use of digital holography: simulation and experimentation

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet

We present a method to image Jones vector by use of digital holography. We demonstrate that with a single hologram acquisition, the method allows to image and to calculate Jones vector and derive the polarization parameters. The principle consists in using ...
