SUMMARY We have developed InGaAs-based VCSELs operating around 1.1 μm for high-speed optical interconnections. By applying GaAsP barrier layers, temperature characteristics were considerably improved compared to GaAs barrier layers. As a result, 25 Gbps 100 • C error-free operation was achieved. These devices also exhibited high reliability. No degradation(More)
