MONDAY, 29 JANUARY 2024, VCQ COLLOQUIUM TALK BY RACHEL GRANGE

Lithium niobate on Insulator and Beyond:
Overcoming Fabrication Challenges for Integrated and Flat Photonics

Nonlinear and electro-optic devices are present in our daily life with many applications: light sources for microsurgery, green laser pointers, or modulators for telecommunication. Most of them use bulk materials such as glass fibers or high-quality crystals, hardly integrable or scalable. Even the fast developments of thin film lithium niobate face the challenging etching of metal-oxides. Therefore, the quest for a non-centrosymmetric material system, easy to fabricate and to scale up while maintaining its functionality is still ongoing. Here I will present our recent advances in top-down fabrication of lithium niobate devices and bottom-up assemblies of randomly oriented nanocrystals or sol-gel to produce nonlinear classical and quantum signals.
