(a) Strain-balanced active region band structure. The design is based on Al_0.63In_0.37As/Ga_0.35In_0.65As/Ga_0.47In_0.53As material system. The layer sequence in nm, starting from the injection barrier, is 2.7/ 2.1/ 0.9/ 3.2/ 2.6/ 0.9/ 3.0/ 2.1/ 1.7/ 2.4/ 1.5/ 1.5/ 2.2/ 1.5/ 1.5/ 2.0/ 1.3/ 1.6/ 1.8/ 1.3/ 1.7/ 2.8/ 1.9/ 2.8/ 2.4/ 2.8. The barriers are in bold font, and the wells are in normal font, the Ga_0.47In_0.53As insertions are in italic, and the underlined layers are doped to n = 1.7 × 10¹⁷cm⁻³. (b,c) Schematic descriptions of two major DFG processes for the strain-balanced design, involving one upper level 5 (4) and two lower levels j, k (j, k = 1, 2, 3. j ≠ k) (b), and two upper levels 4, 5, and one lower level j (j = 1, 2, 3) (c).
