We have studied the optical properties of the AlGaInP/GaInP light emitting diodes (LEDs), with a compressively strained multiquantum well (CSMQW) active layer, emitting at 650 nm. It was found that by introducing a compressive strain into the MQW active layer, we can significantly increase the output power of the MQW LEDs. Furthermore, we have also found that a +0.33% compressive strain can reduce the 10-90% rise time and/or fall time of the AlGaInP/GaInP MQW LEDs from 50 ns to 15 ns.
