摘要:
The demonstration of the first visible resonant cavity light-emitting diodes (RCLEDs) is reported. The devices consist of an InAlGaP strained quantum well active region surrounded by AlAs/AlGaAs distributed Bragg reflectors. Linewidths from 0.9 nm (2.6 meV) to 45 run (12.8 mev) were obtained by varying the cavity quality factor (Q).
