We develop a 3mm large-area photonic-crystal surface-emitting laser (PCSEL) with controlled Hermitian and non-Hermitian optical couplings, as well as an in-plane lattice-constant distribution for compensation of the temperature distribution during continuous-wave (CW) operation. We demonstrate a CW output power of 50 W with a very narrow (
