TOM 5 Resonant Nanophotonics

Probing and exploiting non-Hermitianity in photonics

Massimo Gurioli

university of Firenze, Italy

This is an overview of my activity in this field. We experimentally demonstrated non-Hermitian predictions in photonics as complex modal volumes and non-Lorentzian local density of states in cavities on photonic crystal slabs with relatively low optical losses. We clearly evidenced Fano character, in perfect agreement with numerical and theoretical predictions. Finally we discussed the extension to magnetic light-matter interaction, the link with Fano profiles in atomic absorption and the tailoring of vacuum field trap for excitons.

Efficient coupling of free propagating light into Whispering Gallery Modes

In this work, we show a recently developed analytical model which quantitatively describes the coupling of free propagating beams into Whispering Gallery Modes for spherical particles. Using this model, we have proven that the coupling of light into Whispering Gallery Modes is governed by an Angular Momentum matching condition. Last but not least, we have experimentally verified that the model predicts most of the relevant parameters that are measured in experiments, such as coupling efficiency, field distribution, and spectrum.

We report on the generation of photon pairs via spontaneous parametric down-conversion in nonlinear metasurfaces featuring Mie-type resonances. We obtained a 128-fold enhancement of the pair-generation rate, in comparison with an unpatterned film of the same thickness and material, when both photons are emitted at the sharpest resonance of the metasurface.

Design of erbium doped silicon nanocavities for single photon applications

Matteo Di Giancamillo1,2, Paolo Biagioni2, Vito Sorianello3, Enrico Prati1

1Istituto di Fotonica e Nanotecnologie, Consiglio Nazionale delle Ricerche, Italy; 2Dipartimento di Fisica, Politecnico di Milano, Italy; 3Photonic Networks and Technologies Lab, Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT), Italy

The goal of this research is to design a LED weak photon source for quantum communications in space at 1540 nm, exploiting Er-O complexes generated by erbium implant in a portion of a silicon waveguide. The source is made with materials and processes compatible with CMOS technology and emits photons directly into the optical circuit. We explored the Purcell effect to enhance the radiative emission. Simulations were carried using Ansys Lumerical and Comsol Multiphysics. The results support the feasibility of a device that meets the requirements of operation and manufacture.
