Near-field analysis of surface electromagnetic waves in the bandgap region of a polymeric grating written on a one- dimensional photonic crystal

Hans Peter Herzig, Tristan Sfez, Francesco Michelotti

The spatial distribution of surface electromagnetic waves on a one-dimensional photonic crystal with a polymeric grating on top is mapped using a multiheterodyne scanning near-field optical microscope. The grating opens a bandgap. At the band edges, a stat ...

Engineering the optical response of plasmonic nanoantennas

Olivier Martin, Holger Fischer

The optical properties of plasmonic dipole and bowtie nanoantennas are investigated in detail using the Green's tensor technique. The influence of the geometrical parameters (antenna length, gap dimension and bow angle) on the antenna field enhancement and ...

Terahertz Quantum Cascade Lasers based on two-dimensional photonic crystal resonators

Romuald Houdré, Marcella Giovannini, Jérôme Faist, Lorenzo Sirigu

We demonstrate high spectral control from surface emitting THz Quantum Cascade Lasers based on a two-dimensional photonic crystal cavity. The perforated top metallic contact acts as an in plane resonator in a tight double-metal plasmonic waveguide providin ...

Multi-wavelength digital holographic microscopy for sub-micron topography of reflecting specimens

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Jonas Kühn, Florian Charrière

The study of the internal structures of specimens has a great importance in life and materials sciences. The principle of optical diffraction tomography (ODT) consists in recording the complex wave diffracted by an object, while changing the k vector of th ...

Numerical Optics in Digital Holography

Christian Depeursinge, Tristan Colomb, Frédéric Montfort, Jonas Kühn, Florian Charrière

As digital holography achieves numerical reconstruction of the complex wavefront diffracted by specimen, a numerical optics formalism has been developed: numerical filters replace pinholes in Fourier planes, numerical lenses allow aberrations compensation ...
