Abstract
We have studied the optical properties of the Al-GaInP-GaInP light-emitting diodes (LED's), 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 achieve a much faster operation speed and a higher output power. It was also found that a +0.33% compressive strain can reduce the 10%-90% rise time and/or fall time from 50 to 15 ns. Furthermore, the +0.33% compressive strain can also increase the output power of the MQW AlGaInP-GaInP LED by more than 40%. Such a high operation speed and high output power LED is potentially useful in polymer-based optical fiber communication.
