GIANT unites the vast majority of resources in Grenoble for the study and fabrication of photonic nano/microstructures and materials. GIANT laboratories, institutes and university campuses collaborate in the Grenoble University of Innovation (GUI) project for photonics applications, with particular emphasis on biology (luminescent markers for in vitro studies or in vivo studies on small animals) and astronomy.
Grenoble is also an acknowledged centre for optics and optoelectronics, and has contributed to a number of major industrial successes, including Sofradir and Ulis. With the support of RTRA Nanosciences, laboratories involved in fundamental and applied research have established close collaborative links to explore and apply the full potential of photonics in many fields.

Research in photonics attempts to improve control over the generation, propagation and detection of light using innovative materials and micro and nanostructures. Nanophotonics have progressed rapidly since the beginning of the 1990s, taking advantage of the development of photonic crystals, optical micro-cavities and semiconducting quantum dots. Nanometre-scale electron confinement and/or wavelength-scale confinement of photons have revealed a large number of fundamental physical effects in solid systems.
These new effects are used to develop innovative optoelectronic components, such as single-photon sources, low-threshold lasers, high-efficiency and LEDs. There are also promising new applications in fields such as quantum data processing and quantum communications, lighting, photonic integrated circuits for telecom and datacom applications, high-throughput optical interconnections in or between electronic chips, and biophotonics.
Fields of expertise:
- Engineering, synthesis and experimental study of crystals for lasers and parametric sourcesInnovative semiconducting nanostructures
- Nanoparticles for biosciences
- Production, handling and detection of quantum states of light for quantum cryptography
- Bose-Einstein condensation of excitons-polaritons in semiconducting micro-cavities and polariton lasers
- Silicon photonics, including light generation using “microelectronic compatible” materials
- Hybrid structures and components, including polymer/semiconductor assemblies for photovoltaics
- New, near-field imaging techniques.
Thus, GIANT laboratories have established themselves as experts in the bottom-up synthesis of nanostructures. Since 2007, they also have top-down nanofabrication resources through a new upstream technological platform (PTA) managed jointly by CEA and CNRS. With its cutting-edge electronic lithography and reactive ionic etching equipment, the PTA meets the advanced specifications required for the fabrication of photonic microstructures of the future.
