HINA

The MSCA Doctoral Network HINA project proposes to consider the hybrid integration of alkaline niobate-
tantalate thin films, (K,Na)(Nb,Ta)O3 (KNTN, materials with the highest known experimentally measured
electro-optic, nonlinear, piezoelectric, elasto-optic coefficients) in photonic and acoustic devices for
advanced semiconductor photonics platforms. The final goal of the project is to develop a thin film technology
not only offering the state-of-the-art performances but also with reasonable price and viable for real industrial
applications in order to stimulate the transfer of newly developed products and technologies by the industry
and to help enterprises to withstand global competitive pressures. This project is coordinated by the
University of Marie and Louis Pasteur / Institute FEMTO-ST and funded by the Horizon Europe program
under the Marie Skłodowska-Curie Actions. Project website: https://msca-dn-hina.eu

Objectives: 

Small size and high frequency (> 6 GHz) SAW resonators based on KNTN with high K2 for
acousto-optic transducers and acoustic wave coupling with spin waves: (i) develop design techniques for
novel SAW devices (ii) modelling and simulation of SAW resonators based on literature data using COM
model or the P-matrix models (ii) building on well-known models from literature and the models will be
adapted to the new materials and structures models for SAW resonators and filters with new materials (iii)
novel SAW resonators designs based on measured KNTN film properties; (iv) FEM modelling and simulation
allows a deeper look in the physics of the resonators to optimize them in term of losses (acoustic, electrical)
and energy confinement; (iv) innovative designs for guided SAW based resonators with reduced footprint.
