摘要：

High efficiency substrate emitting microcavity InGaAs/(Al)GaAs 3 QW LEDs are reported. The use of regrowth for cavity resonance tuning and its effect on device performance, are demonstrated. The best results obtained include external quantum efficiencies of 16%. At 5mA, 1mW optical power is delivered with an intensity of 280 mu W/sr.
