摘要：

A maximum output power of 115 mW and a slope efficiency of 0.92 W/ A have been achieved in 0.98-μm InGaAs strained quantum well lasers with a 3-μm-wide ridge waveguide structure for efficient fiber coupling. Stable operation of over 5000 h under 50†C constant power operation with an optical power density of 3.9 MW/cm2 has been demonstrated with a degradation rate as low as 5 x 10 -6 per hour. These results show this device is promising as a practical pumping source for Er3+-doped fiber optical amplifiers. © 1990 IEEE
