Optical Amplification with Large Goos-Hnchen Shift Driven by Non-Hermitian Bilayer Meta-Grating Under Lasing State
Ma Luo, Xueyi Zhang
The coexistence of gain and loss in parity-time symmetric bilayer meta-gratings enables the transformation of bound states in the continuum into a ring of lasing threshold modes. U…
