Topological polarization singular lasing with highly efficient radiation channel

HIGHLIGHTS

• who: Yun-Gang Sang from the (UNIVERSITY) have published the paper: Topological polarization singular lasing with highly efficient radiation channel, in the Journal: (JOURNAL) of 25/02/2022
• what: The authors demonstrate a topological polarization singular laser which has a topological polarization singular channel in the second Brillouin zone and a paired linearly polarized radiation_channel in the first Brillouin zone. The authors propose a cavity with two radiation_channels with distinct topological features. To reveal the distinct topological features of the radiation field of a Bloch mode in different Brillouin zones, the authors design the photonic . . .
