Abstract：The optics community has used since decades lithium niobate material for various application like optical modulation, lasers, acousto-optical devices etc. Due to its multiphysical nature (it possesses high electro-optic, acousto-optical, photorefractive, pyroelectric, and nonlinear coefficients), it is rather straightforward to imagine a lithium niobate chip in which thousands of optical functions could be incorporated.

In my talk, I will present the work that my group at CNRS has been doing since the last 10 years in order to achieve this goal. Different active optical functions based on lithium niobate photonic crystals and plasmonic nanostructures combined with lithium niobate will be presented. The possibility of currently working with lithium niobate thin films on SiO₂ has allowed us to radically improve the optical performances of these devices. Results on novel photonic nansotuctures based of single crystal lithium niobate will we shown. At last, the application of tunable Fano lithium niobate photonic crystals attached to an optical fiber for electric field sensing will be also demonstrated.
