Chiral Surface Waves for Enhanced Circular Dichroism
Giovanni Pellegrini, Marco Finazzi, Michele Celebrano +2
We present a novel chiral sensing platform that combines a one-dimensional photonic crystal design with a birefringent surface defect. The platform sustains simultaneous transverse…
Local field enhancement: comparing self-similar and dimer nanoantennas
Giovanni Pellegrini, Michele Celebrano, Marco Finazzi +1
We study the local field enhancement properties of self-similar nanolenses and compare the obtained results with the performance of standard dimer nanoantennas. We report that, des…
Monolithic AlGaAs second-harmonic nanoantennas
V. F. Gili, L. Carletti, A. Locatelli +9
We demonstrate monolithic aluminum gallium arsenide (AlGaAs) optical anoantennas. Using a selective oxidation technique, we fabricate such epitaxial semiconductor nanoparticles on…
