P TSymmetric Large Area Single Mode DFB Lasers
We propose a novel class of large-area single-mode semiconductor lasers in which notions from parity-time symmetry is employed to reliably suppress higher-order modes. The feasibility of our design is investigated in InGaAsP quantum-well arrangements.doi:10.1364/cleo_qels.2014.fm1d.3 fatcat:3jbmp6jlavggjewp3is2ck5stu
