Abstract :
Single-quantum-well, separate-confinement double-heterostructure laser diode arrays which exhibit a high power conversion efficiency of greater than 54% have been demonstrated. The high efficiency results from a low internal loss of 3cm1 and high internal conversion efficiency. The maximum output power for a 100¿m emitting aperture is 2 W CW and is independent of the cavity length.
