Non-Hermitian gauged laser arrays with localized excitations: Anomalous threshold and generalized principle of selective pumping
Li Ge, Zihe Gao, Liang Feng
We investigate non-Hermitian skin modes in laser arrays with spatially localized excitation. Intriguingly, we observe an unusual threshold behavior when selectively pumping either…

Rate equation analysis and non-Hermiticity in coupled semiconductor laser arrays
Zihe Gao, Matthew T. Johnson, Kent D. Choquette
Optically-coupled semiconductor laser arrays are described by coupled rate equations. The coupled mode equations and carrier densities are included in the analysis, which inherentl…

Parity-Time Symmetry in Coherently Coupled Vertical Cavity Laser Arrays
Zihe Gao, Stewart T. M. Fryslie, Bradley J. Thompson +2
We report parity-time (PT) symmetry breaking in electrically injected, coherently coupled, vertical cavity surface emitting laser arrays. We predict beam steering, mode evolution a…
