Title:  Lithium niobate integrated photonics

Speaker: Qiang Lin (University of Rochester)

Abstract:  In this talk, I will present our recent progress in lithium niobate integrated photonics. Lithium niobate (LN) exhibits outstanding electro-optic, nonlinear optical, and piezoelectric properties and has become a workhorse material system for photonics industry and photonic research and development. Photonic integrated circuits (PICs), on the other hand, offer exceptional capability for controlling light flow, light confinement, and light-matter interaction. Combining these excellent worlds together into a LN PIC platform opens up a great opportunity for realizing novel functionalities beyond the reach of conventional means. I will discuss our recent efforts in developing optical frequency comb, wavelength conversion, electro-optic signal processing, and quantum entanglement on this platform. I will also give a brief overview of the background, discuss some current challenges and opportunities of the fields, and provide my personal outlook.
