Claim 10:
11. The passthrough semiconductor optical amplifier of claim 10, wherein the N-type confinement layer comprises (i) a first confinement sublayer having a thickness between 5 and 15 nm with a bandgap between 0.9 and 1.1 eV attached to a barrier layer with a bandgap between 0.9 and 1.1 eV next to the lower portion of the N-doped active layer and (ii) a second confinement sublayer having a thickness between 15 and 80 nm and a bandgap between 1.1 and 1.2 eV attached to a side of the first confinement sublayer more distal to the N-doped active layer than the first confinement sublayer.
