摘要: A single-mode light-emitting-diode (LED) can have many of the favorable coherence properties lasers, while being a more reliable, threshold-less, device. Progress in electromagnetic micro-cavities, such as those formed by photonic band structure, allow all spontaneous emission (of an LED) to be funneled into single mode. It is shown that internal quantum efficiency GaAs/AlGaAs double heterostructures high 99.7%, and consequently, external shot-noise suppression LEDs comparable semiconductor but at much lower injection level.
