Dynamic control of light transmission through multimode fibers

Ioannis Papadopoulos

In the present thesis we demonstrate how under the appropriate dynamic control of light propagation, multimode fibers can be transformed into deterministic optical elements that along with their ultrathin size, large number of degrees of freedom and high N ...

Multiple Phase Anomalies in Bessel Beam

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

The non-diverging feature of the Bessel-kind beam leads to multiple phase anomalies along the optical axis in contrary to the focused Gaussian beam. Here, we analyze the phase distributions using in a longitudinal-differential phase mode of a high-resoluti ...

Switchable telescopic contact lens

We present design and first demonstration of optics for a telescopic contact lens with independent optical paths for switching between normal and magnified vision. The magnified optical path incorporates a telescopic arrangement of positive and negative an ...

Full field vertical scanning in short coherence digital holographic microscope

Christian Depeursinge, Christophe Moser, Etienne Cuche, Frédéric Montfort

In Digital holography Microscopes (DHM) implemented in the so-called "off axis" configuration, the object and reference wave fronts are not co-planar but form an angle of a few degrees. This results into two main drawbacks. First, the contrast of the inter ...

Curved Transflective Holographic Screens for Head-Mounted Display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Arnaud Mader, Victor Javier Cadarso Busto, Jonas Grossenbacher, Seyedpayam Vahdati

A volume hologram recorded with a lens array is proposed as a transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a projection system, with similar properties to one mounted on ...

Third-harmonic generation microscopy with Bessel beams: a numerical study

We study theoretically and numerically third-harmonic generation (THG) from model geometries (interfaces, slabs, periodic media) illuminated by Bessel beams produced by focusing an annular intensity profile. Bessel beams exhibit a phase and intensity distr ...
