Optical properties of nano-structured materials studied by means of interferometric techniques

Tortora, Pierpasquale ; Herzig, Hans Peter (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2005 ; 1843.

In this thesis work we avail ourselves of optical interferometric techniques for the study of the optical properties of nano-structured materials. As a first step, we set up a multiple heterodyne scanning probe optical microscope (MH-SPOM). This apparatus allows to detect amplitude and phase of the optical field with sub-wavelength resolution. In addition, it is provided with other two...

Properties of light fields near sub-micro and nano-scale structures

Rockstuhl, Carsten ; Herzig, Hans Peter (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2004 ; 1786.

In this thesis various phenomena that appear if light interacts with objects having a size comparable to the wavelength are experimentally and theoretically analysed. The work is concentrated on the analysis of phase singularities in electromagnetic fields, on the excitation of plasmon-polaritons and phonon-polaritons in arbitrary shaped cylindrical objects and on the analysis of force and torque...
