Hybrid Electro-Photonic Circuits made through dynamic machining and assembling – CEPAGE

Submission summary

While photonics is emerging as an attractive alternative to electronics in high bit rate telecommunication systems, sensors or signal processing devices, there is a need of specific 3D photonic architectures that cannot be easily engineered by clean-room processes. As an example, detection applications would benefit from thin-plate-based polarization controllers, or from photonic waveguides in non-standard electro-optic materials. But the production and integration of these building blocks is far from being trivial. The CEPAGE project addresses this issue by proposing two innovative approaches. The first one relies on the development of technologies enabling the machining of "exotic" substrates for the production of innovative electro-photonic waveguides and resonators confining light in very small cross section (~1µm2). The project specifically targets the machining of cubic electro-optic materials (BSO, BGO, ZnTe ...) that show an isotropic behavior in the absence of applied electric fields, which is of great interest for sensing applications. The second innovation relies on the dynamic assembling of photonic building blocks (waveguides, resonators, thin plates) for the development of new 3D hybrid electro-photonic circuits. This approach makes possible the integration of thin metamaterial-based layers controling the polarisation, and it gives the opportunity to make the best choice of material and technology for each of the photonic building blocks. Moreover, by dynamically optimizing the positioning and the assembling of the photonic building blocks, the approach allows optimized photonic circuits with minimal waste.
Two complementary industrial applications will be developed. The first application will be a compact temperature-independent Electro-photonic sensor for the detection and measurement of electric fields over large range of frequencies, principally for Electro-Magnetic Compatibility (EMC) market. The second application will consist of a Chipscale optoelectronic Gyroscope for 3D stabilization of vessels or inertial navigation of drones.
In addition to the valuation and prospects related to the attractive properties of the studied materials and configurations, the project opens up an interdisciplinary research field at the boundary between micro-optics, photonics and robotics for gripping, handling and assembling photonic elements .
An efficient transfer of the technological developments toward the industrial sector is guaranteed by the commitment of three companies (iXblue PSD, Kapteos, Kylia) and one partnership foundation (FEMTO-Engineering) working in the project team in collaboration with the FEMTO-ST institute. This project is also the opportunity to combine multidisciplinary skills that will get involved in the training courses and in the formation of the University of Besançon. Consequently, the project presents a training aspect and it falls within the axis of the SMYLE (Smart sYstems for a betterLifE) collegiums and of the “Cursus Master en Ingénierie” (CMI) devoted to physics and electronics.
