Offer Description

Transparent ferroelectric oxides with strong second-order nonlinearity are essential platforms for electro-optical and nonlinear photonics. The ELLIPTIC focuses on Lithium Tantalate-on-Insulator (LTOI) technology, a platform offering compatibility with large-scale microelectronic manufacturing. Besides integrated photonic circuits, one goal of the project is the design and demonstration of functional optical metasurfaces for free space applications. Exploiting LTOI’s high second-order nonlinearity and strong Pockels effect, we target efficient nonlinear frequency generation and tunable flat optics with dynamic wavefront control. Additionally, phonon-polariton resonances at THz frequencies enable extreme light confinement and ultra-sharp responses. The early-stage researcher will be involved in the analysis and design of metasurfaces, including optimization and machine learning approaches.
