Lithium niobate (LN), the workhorse of optoelectronics, is an excellent photonic material with large electro-optic coefficient, Kerr nonlinearity and piezoelectric response, and a wide optical transparency window. Recent advances in nanofabrication technology have allowed for the realization of ultra-low loss LN waveguides and are opening exciting opportunities for next-generation nonlinear photonic technologies with higher integration density and advanced functionalities. In this talk, I will review our recent developments of thin-film LN devices, including optical frequency combs, supercontinuum generation, optical frequency shifting, acousto-optic control. In addition, I will discuss the potential of LN platform for applications in nonlinear frequency conversion, frequency metrology, and microwave photonics.
​
Following the technical talk, I will give a  short professional development talk, including networking and volunteering in the photonics community, and I will cover some career advice for graduate students.
