Description

Abstract:  The ability to manipulate photons is of critical importance for both fundamental quantum optics studies and practical quantum photonic applications. While integrated photonic circuits provide the unprecedented power to realize complex photon control with minimized structures, most materials used in integrated photonic circuits lack the preferred second-order optical nonlinearity, which greatly limits photon control functionalities. On the other hand, recent development of novel nonlinear photonic platforms with strong second-order nonlinearity including aluminum nitride and lithium niobate can provide new aspects and enable novel methods for quantum photon control 
In this talk, I will present our effort in developing quantum engineering technology based on nonlinear integrated photonics. We will start with the generation of various quantum states including quantum frequency comb and squeezed light. Then, we will introduce the quantum photonic analogue of Mollow triplet with on-chip photon pair generation in dressed modes. At last, I will focus on our theoretical work about high-dimensional frequency-encoded quantum information processing with passive photonics and time-resolving detection. 
 
Bio: Linran Fan received his B.S. in physics from Peking University in 2011, and his PhD in electrical engineering from Yale University in 2017. He finished his postdoctoral research at Caltech from 2017 to 2018. He is now an assistant professor in Wyant College of Optical Sciences at the University of Arizona. His research interests focus on the development of on-chip photon control technology using nonlinear optical, mechanical, and electro-optic effects at nanometer scale with applications targeting quantum and classical information processing.
