PZT & Graphene Innovations for Multiple Functionalities in a Miniaturized Footprint

Europe’s leading position in photonics and electronics can only be secured by adapting to the next generation of optoelectronic device requirements: high performance, multi-functionality and cost efficiency in miniaturized footprint. These can only be achieved if novel schemes for on-chip integration emerge.

Among the established platforms for optoelectronic integrated circuits (OEICs), silicon nitride as a wide-band and low-loss material stands out, however, on its own, it has no active effect. Hence, the newly funded Horizon Europe project MatEl aims to introduce novel on-chip integration schemes enabled by innovative laser processing of advanced materials, such as graphene or PZT.

In the period of three and a half years, beyond the state-of-the-art technologies of Laser Digital Processing (Laser Transfer and Laser Soldering) will be employed for the accurate and fast alignment and bonding of chip packages (OEIC) on Si3N4. The resulting hybrid platform will be enhanced by the monolithic integration of advanced materials (graphene and high-quality PZT), which will enable multiple functionalities in a miniaturized footprint.

Overall, MatEl ’s hybrid platform will combine the wide bandwidth and high confinement provided by Si3N4 with the active functionality of III-V and II-VI lasers.

MatEl aims to demonstrate the universal vision of the project on two TRL5 applications in Augmented Reality (AR) and advanced biosensing. These diverse demonstrations can in turn contribute to accelerating the adoption of hybrid OEICs across industries and to strengthening the EU photonics and microelectronics industrial capability.
