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.

Analysis of the Multichannel WDM-VLC Communication System
TL;DR: In this article, the maximum number of channels and possible data rate in a WDM-VLC system based on light emitting diode (LED) was investigated by modeling LED spectra and the formula for crosstalk is derived from VLC link, including optical filter transmittance and detector spectral response.
