Abstract

Temperature-insensitive vertical-cavity surface-emitting lasers (VCSELs) are promising devices for low-cost optical interconnection. The authors measured the injection current at a threshold and light output power of 1 mW at temperatures of 20, 50 and 80°C. At 80°C and 1 mW, the driving current for VCSELs with a broad gain bandwidth was reduced by ~20%, compared with that for conventional VCSELs. The deviation in driving current for VCSELs with a broad gain bandwidth was ~10%, which demonstrates that these VCSELs have uniform temperature characteristics in an 8×8 array
