Electronics, magnetics and photonics


Hybrid photonics: integration, design and devices

The goal of this symposium is to discuss and highlight recent advances on hybrid integration of novel materials for integrated optics and nanophotonics. That includes a large variety of materials: oxides, chalcogenides, polymers, III-V, halide perovskites, diamond, 0D, 1D and 2D nanomaterials, etc... and their monolithic or hybrid integrations with more standard photonics platforms (Si, Ge, III-V).


Photonics is a key enabling technology with countless applications ranging from on-chip optical communications to sensing, quantum technologies or security, to name a few. Recently, the emergence of nanophotonics and optical metasurfaces have opened unprecedented ways to control light fields at the nanoscale that further expands the potential of this technology.
For several years, the progress in photonic devices has been governed by the development of passive and optoelectronic devices based on III-V and Si materials. At optical frequencies, nanophotonic systems are patterned at the micro- and nano-scale, resulting in building blocks with geometries and arrangement that are defined via fabrication processes.
The future evolution of photonic integrated circuits calls for multifunctional properties as well as higher performances in terms of power consumption, efficiency, footprint and speed. This opens up new opportunities for the heterogeneous integration of functional materials with exceptional optical properties. New challenges on light-matter interactions and optical integration for large-scale manufacturing have also to be addressed that will rely on the development of innovative concepts using emerging materials with tailored optical properties.

A large variety of efficient optical materials including functional oxides, electro-optic materials, phase-change materials, polymers, liquid crystals, hybrid perovskites, carbon-based materials (diamond, carbon nanotubes and graphene), 0D, 1D and 2D nanomaterials as well as electro-mechanical materials can be considered which would all find a perfect showcase in the framework of this symposium.
The symposium aims to gather experts working at the theoretical and experimental level on the development of novel materials for integrated photonic applications.
