Abstract

In this talk, I will discuss the recent advances in exploring novel photonics with the construction of synthetic frequency dimension through the electro-optic modulation, where light can be manipulated in linear and nonlinear ways. In particular, I will discuss the way to construct a one-dimensional Lieb lattice and explore the transition between flat and non-flat bands in the synthetic space. Our work shows a significant step towards constructions of more complicated lattices in multiple rings. Moreover, I will propose a unique method to explore the topological non-equilibrium dynamics and capture the topological invariant with information only in the time dimension, by building an effective spin model in multiple rings associated with synthetic frequency dimensions. Finally, I will talk about the opportunity for studying nonlinear effects in the synthetic space, once the four-wave mixing process is considered.
