Highly reliable 1.3 μm AlGaInAs FP lasers with low power penalty under uncooled 10Gbps operation at 85°C

We have realized highly reliable 1.3 μ m AlGaInAs FP lasers with low power penalty of 1.4dB at 10Gbps and 85°C. The MTTF was estimated over 1.5×105 hours and no deterioration of COD level was observed during the life test.
