Probing the optical near-field interaction of Mie nanoresonators with atomically thin semiconductors

Ana Estrada‐Real, Ioannis Paradisanos, Peter R. Wiecha, Jean‐Marie Poumirol et autres

Abstract Optical Mie resonators based on silicon nanostructures allow tuning of light-matter-interaction with advanced design concepts based on complementary metal–oxide–semiconductor (CMOS) compatible nanofabrication. Optically active materials such as transition-metal dichalcogenide (TMD) monolayers can be placed in the near-field region of such Mie …

Exciton spectroscopy and unidirectional transport in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride

Dorian Béret, Ioannis Paradisanos, Hassan Lamsaadi, Ziyang Gan et autres

Abstract Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures. Critical for carrier and exciton transport is the material quality and the nature of the lateral heterojunction. Important details of the optical properties were inaccessible in as-grown heterostructure …

Generalizing the exact multipole expansion: density of multipole modes in complex photonic nanostructures

Clément Majorel, Adelin Patoux, Ana Estrada‐Real, Bernhard Urbaszek et autres

Abstract The multipole expansion of a nano‐photonic structure’s electromagnetic response is a versatile tool to interpret optical effects in nano‐optics, but it only gives access to the modes that are excited by a specific illumination. In particular the study of various illuminations …

Inverse design with flexible design targets via deep learning: Tailoring of electric and magnetic multipole scattering from nano-spheres

Ana Estrada‐Real, Abdourahman Khaireh-Walieh, Bernhard Urbaszek, Peter R. Wiecha

Deep learning is a promising, ultra-fast approach for inverse design in nano-optics, but despite fast advancement of the field, the computational cost of dataset generation, as well as of the training procedure itself remains a major bottleneck. This is particularly inconvenient because …

One pot chemical vapor deposition of high optical quality large area monolayer Janus transition metal dichalcogenides

Ziyang Gan, Ioannis Paradisanos, Ana Estrada‐Real, Julian Picker et autres

We report one-pot chemical vapor deposition (CVD) growth of large-area Janus SeMoS monolayers, with the asymmetric top (Se) and bottom (S) chalcogen atomic planes with respect to the central transition metal (Mo) atoms. The formation of these two-dimensional semiconductor monolayers takes place …
