Submicron hollow spot generation by solid immersion lens and structured illumination

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the experimental and numerical demonstration of immersed submicron-size hollow focused spots, generated by structuring the polarization state of an incident light beam impinging on a micro-size solid immersion lens (μ-SIL) made of SiO2. Such s ...

Diffraction and absorption enhancement from textured back reflectors of thin film solar cells

Christophe Ballif, Franz-Josef Haug, Ali Naqavi

We study light scattering and absorption in thin film solar cells, using a model system of a sinusoidally textured silver reflector and dielectric layers of ZnO and amorphous silicon. Experimental results are compared to a theoretical model based on a Rayl ...

Controlling and utilizing optical forces at the nanoscale with plasmonic antennas

Olivier Martin, Andrea Lovera

Plasmonic dipole antennas are powerful optical devices for many applications since they combine a high field enhancement with outstanding tunability of their resonance frequency. The field enhancement, which is mainly localized inside the nanogap between b ...
