Ultrahigh-brightness 850 nm GaAs/AlGaAs photonic crystal laser diodes
K. Posilovic, T. Kettler, V. A. Shchukin, N. N. Ledentsov, U. W. Pohl et al.
One-dimensional photonic crystal lasers emitting in the 850 nm range show high internal quantum efficiencies of 93% and very narrow vertical beam divergence of 7.1 degrees (full width at half maximum). 50 [mu]m broad area lasers with unpassivated facets exhibit a high total output power of nearly ...
