We describe a new InGaP/lnGaAs/GaAs quantum well laser structure, the SPIN (Spread INdex) laser design. The figure of merit for the 980 nm Er-doped fiber application is how much power is coupled into the single-mode fiber. This is determined by the beam divergence and external differential quantum efficiency. To this end, the SPIN laser design allows a nearly symmetrical beam divergence, while maintaining high external differential quantum efficiency. The laser structure was grown by low pressure (45 Torr) metalorganic chemical vapor deposition (MOCVD).
