High output power devices at 25°C. (a) L-I-V curve from a 685 nm device with a single large aperture, demonstrating a peak output power of 14 mW. (b) L-I-V from a 680 nm device with multiple apertures in a 200 μm × 200 μm area, demonstrating a peak output power of 44 mW (from Proceedings of the SPIE, Vol. 7952, paper 795208).
