This research finds its roots in the general problematic of multifunctional integration of optics in systems to improve their functionality, their energetic and technological footprints, etc… This research direction stems from and furthers the past developments which were geared towards the improvement of laser sources, devices which lie at the very heart of photonics systems.
In recent years, novel research strands have emerged in response to the ever increasing demands for new integrated solutions to create embedded optical sensing devices (imaging, hyperspectral imaging and sensing, vision….) . The research work is organized along three main axes ranging from the integration of optics in systems and subsystems to nano-engineered materials, through advanced devices.

At the system level, activities focus on the demonstration of advanced optical systems and subsystem for free space optics application. The core research relies on  using innovative components together with heterogeneous integration using micro-nano-electronic-technologies to answer the key challenges of integration robustness, conception complexity and development cost.
Research at the device level focuses on two key families that are optical filters and advanced sources, trying to demonstrate novel rupturing technologies responding either to applicative demands expressed in systems conception or using novel engineered materials properties.
At the material level, we exploit the ability of engineering the collective properties and functions of III-V materials and heterojunctions through their nanoscale structuration. This is investigated by using complementary bottom up or top down approaches. The ultimate goal is to merge these two complementary approaches to fully develop 3D integration schemes for both electronic and photonic properties of materials, enabling generation of artificial materials with tailored optoelectronic properties.

These research activities require the development of technological building blocks and relies on novel integration concepts.
