Proposed electrically pumped laser array shows improved emission power and side-mode suppression, indicating advancements in laser technology.
We propose an electrically pumped single-mode semiconductor Fabry-Perot laser array based on Parity-Time symmetry. The emission power and side-mode suppression ratio are about five times and six times higher, respectively, compared to conventional Fabry-Perot laser.
