The chiral interaction between light and matter has brought chiral quantum optics into a ﬂourishing stage. Here, we explore the perfect chiral interaction between the atoms with elliptically polarized dipoles and waveguide modes, and ﬁnd that ideal unidirectional radiation can be obtained by adjusting the position and polarization of atoms. When there are two waveguide modes in the system, by controlling the polarization of the dipoles, the dipoles can radiate not only the unidirectional single waveguide mode, but also two seperated waveguide modes.

“…However, previous reports on PSHE have been relatively simple, primarily focusing on the directional propagation of a single-mode in two-dimensional configurations [8][9][10][11][12][23][24][25]. While these studies have provided valuable insights, the chiral interactions between atoms and waveguide modes remain an underexplored domain.…”
