In this talk, I will discuss several new topics on the controlling of light on a small scale.  These topics include a non-Hermitian topological effect in which one can pump a material uniformly yet gain only shows up on the edge; a parity-time symmetric non-reciprocal effect that light only goes one way in a waveguide; and the passive radiative cooling and heating textiles embedded with nanophotonic structures. These topics highlight the unprecedented capabilities of nanophotonic structures in photonic integration, information processing, and sustainable energy.


Dr. Alex Y. Song is currently a postdoctoral scholar in the E. L. Ginzton Laboratory and the Department of Electrical Engineering at Stanford University. He received his Ph.D. in Electrical Engineering from Princeton University. He completed his B.S. in Mathematics and Physics, and M.S in Electrical Engineering at Tsinghua University.
