Abstract

We report that an 850 nm VCSEL with a planar higher-order mode absorber formed by shallow Zn diffusion (< 0.3 μm deep) operated at stable single- mode. A 5 μm square device showed single-mode emission with a ~ 0.8 mA threshold, a 2.2mW maximum output power, and a mode suppression ratio of 40 dB.
