摘要: A planarity preserving method for the definition of vertical‐cavity surface‐emitting lasers (VC‐SEL) is described. strained‐layer InGaAs quantum well VC‐SEL structure was grown and were laterally defined using a tailored deep proton implantation process. In these we obtained low threshold current densities 1000 A/cm2 efficient cw operation. This facilitates large‐scale integration devices.
