Abstract
The light-emitting diode includes first and second layers of semiconductor material, having opposite conductivity types, an active light-emitting area located between the first and second layers of semiconductor material, an electrode arranged on the first layer of semiconductor material and a photonic crystal formed in the first layer of semiconductor material. The photonic crystal and the electrode are separated by a distance optimized to simultaneously promote the electric injection and minimize the light absorption in the LED.
