Abstract
The long-term reliability of AlGaInP/GaInP strained multiquantum well (SMQW) lasers has been investigated. Highly stable operation with low operation current for more than 5500 h has been achieved under 50 degrees C, 3 mW test conditions, without sudden or rapid failures due to strain induced defects. The estimated mean time to failure (MTTF) is 10900 h, which is comparable to that of the conventional DH laser and long enough for practical use.
