University of Graz (Austria)
Controlled excitation and measurement of multipoles in nanoscatterers is an important task of increasing interest in nano-optics and nano-metrology. Here, we discuss the implementation of a far-field approach for the retrieval of multipolar contributions to particle scattering. We utilize a reconfigurable photonic integrated circuit capable of measuring spatial phase, polarization and intensity information. We introduce the multipole retrieval scheme and discuss the main concepts of this novel detector, paving the way towards intriguing applications in nano-metrology, microscopy and imaging.

Herein, we present the enormous capabilities of the most recent rediscovered 2D material named black phosphorous (BP). It offers a solution for several technological limitations that appears in conventional 2D materials such as transition metal dichalcogenides/oxides etc. In the present work, we have demonstrated the electronic and optoelectronic properties of BP via realizing field effect transistors.

Technical University of Denmark (Denmark)
Microrobots are rapidly developing as a valuable solution for performing microscale tasks, among which they seem particularly promising for biomedical and environmental applications. Two-photon polymerization enables the fabrication of microstructures with complex shapes, while focused laser beams allow for precise manipulation of such 3D printed objects. Whereas several challenges have yet to be overcome before microrobots can perform in the real world, many interesting laboratory applications have already been demonstrated, while others are being explored.

We give both analytically and numerically a demonstration of the possibility to realize a simple plasmonic demultiplexer based on Fano and electromagnetic induced transparency resonances. The demultiplexer consists in a waveguide with an input line and two output lines. Each output line contains two stubs placed at two different positions. We derive the expressions for a selective transfer of a single propagating mode through one line keeping the other line unaffected. The analytical results are confirmed by numerical simulations.

15:50 Invited talk: Shapeshifting diffractive optical elements
online, on-demand
Antonio Ambrosio
Istituto Italiano di Tecnologia (Italy)
We have proved that it is possible to realize optical elements with theory-matching efficiency and practical use, reconfigurable on demand right where and when needed. I will present diffraction optical elements with efficiency equal to the theoretical efficiency, realized by direct structuring of the surface of a photosensitive polymer, avoiding any further development step.
