Origin of efficiency droop in GaN-based light-emitting diodes
Min-Ho Kim,Martin F. Schubert,Qi Dai,Jong Kyu Kim,E. Fred Schubert,Joachim Piprek,Yongjo Park +6 more
TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.

Reliability evaluation for Blu-Ray laser diodes
Matteo Meneghini,Nicola Trivellin,Kenji Orita,Masaaki Yuri,Tsuyoshi Tanaka,Daisuke Ueda,Enrico Zanoni,Gaudenzio Meneghesso +7 more
TL;DR: The results obtained within this paper suggest that the degradation of the laser diodes is correlated to the increase in the non-radiative recombination rate, with subsequent worsening of the optical properties of the devices.

The influence of source impedance on the electrooptical switching behavior of LED's
TL;DR: In this paper, it was shown that the application of a reverse current pulse to the LED will reduce the light-fall time below the value given by the diode time constant, thus offering a simple method of determining the latter without using a photodetector.
