CHALLENGES IN MICRO- AND NANO-OPTICS (plenary talk)
Author(s) :
Herzig, Hans Peter
Description :
Micro-optics describes a family of elements and systems fabricated by modern micromachining. Optical structures with nearly arbitrary shapes and dimensions down to the nanometer can be realized offering a large degree of freedom for the design. The progress in novel light sources, detectors, materia...

Properties of light fields near sub-micro and nano-scale structures
Description :
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 an...

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

Holographic optical elements (HOE) for semiconductor lasers
Author(s) :
Herzig, Hans-Peter
Description :
A two step method is described to produce off-axis holographic lenses with high diffraction efficiency and without astigmatism for semiconductor lasers. The hologram is recorded in the visible (514 nm) and reconstructed in the infrared (800 nm). The principal parameters (recording and reconstruction...

Opportunities in microstructured photonics
Description :
The progress in novel light sources, detectors, materials and technology enable new opportunities and challenges for diffractive optics and nanoscale photonics. Important are also analysis tools, such as near-field imaging (SNOM). Only structures that can be characterized can be fabricated

High resolution displacement detection by speckle pattern analysis : accuracy limits in linear displacement speckle metrology
Description :
We propose a simple reflection measurement setup and a motion evaluation procedure based on a two dimensional recording of subsequent speckle images. The averaging of cross correlation functions is used to measure displacements. We demonstrate experimentally a 10 nm precision on a 50 μm measurement ...
