| Title: Chiral transmission based on EP encircling in nano-optics circuits | |
| Abstract: Chiral transmission can find potential applications in on-chip optical isolators and non-reciprocal mode converters. In this talk, we will report our recent research on chiral transmission based on EP encircling in nano-optics circuits: 1) Based on the mechanism of Hamiltonian hopping for asymmetric mode transmission, a new method for developing asymmetric transmission devices is established, which overcomes the issues of low efficiency with existing asymmetric transmission devices; 2) Fast encircling of EPs can relax adiabatic constraints, hence shorten the asymmetric transmission device length; 3) An efficient gain-free, broadband asymmetric polarization-locked device is realized by encircling exceptional points on the Riemann Riemann sphere. | |
| Biography: Lin Chen is currently a Professor at Wuhan National Laboratory for Optoelectronics, Huazhong University of Science and Technology. Before joining HUST, he was a Postdoctoral Fellow at McMaster University, working with Profs. Weiping Huang and Xun Li. He received his Bachelor in Physics from Wuhan University in 2005, PhD in photonics from the same University in 2010 under the supervision of Prof. Guoping Wang. His current interest focuses on plasmonics, metamaterials, topological photonics, silicon photonics, and their applications.
