Layered component with quantum well structure for yellow light emission, includes reflective layer which returns fraction of the light reflected from the exit structures, back to light exit structures, before it can return into active layer
Layered component with quantum well structure for yellow light emission, includes reflective layer which returns fraction of the light reflected from the exit structures, back to light exit structures, before it can return into active layer
Between active layer (4) and light exit structures (60), a reflective layer (70) intervenes. This has a number of beam windows (71). Through these, electromagnetic radiation produced in the active layer, reaches exit layer (6). The reflective layer returns a fraction of the light reflected from the exit structures, back to structures (60), before it can return into active layer (4). An Independent claim is included for the method of manufacture.
