Abstract

In this project, we will microfabricate optical cavities optimize the fabrication procedures in order to explore the parametric down conversion (PDC) nonlinear process. We will fabricate the optical cavities on lithium niobate (LiNbO3) thin films by using electron beam lithography and plasma etching. In the second stage, two parameters will be optimized: optical losses (characterized by the measurement of optical quality factor) and phase matching (characterized by dispersion measurement). (AU)
