Light emitting diodes with high external quantum efficiency |
摘要 |
A surface emitting light emitting diode (LED) has a reflecting element to redirect light emitted away from the light emitting region towards an exit window. The LED bottom contact is formed over the reflecting element and a current confining path is set up within the LED to funnel current between the top and bottom contacts around the reflecting element and through the light emitting region.
