Abstract    Fabrication of ultrafast nonlinear photonic crystals is often challenging and requires unique processing conditions due to inherent material properties, e.g. high etch resistance, of nonlinear optical materials.  Top-down approaches are well-suited for semiconductor based devices but becomes more difficult for perovskite based nonlinear materials such as lithium niobate (LiNbO3) or barium titanate (BaTiO3).  Therefore, we propose to demonstrate solution-based processing for the fabrication of nonlinear photonic crystals, via nanoparticle dispersions of such perovskite materials, which is a combination of bottom-up processing and imprint lithography that allows for 2D and 3D photonic structures to be created in a straightforward manner.  The long-term goal of this project is to create miniaturized integrated devices, e.g. wavelength-division multipliers (WDMs), molecularly sensitive sensors, which will lead to technology spin-off opportunities, by facilitating and accelerating the fabrication of sophisticated optical components with nonlinear optical nanomaterials.
