Light emitting diode with reduced far-field radiation pattern variation

The present invention relates to reducing the spatial variation in light output from flipchip LEDs and increasing the consistency in light output from LED to LED in a practical manufacturing process. The present invention introduces appropriate texture into the surface of reflective layer to reduce spatial variation in far-field intensity. At least two reflective planes are provided in the reflective contact parallel to the light emitting region such that at least two interference patterns occur in the light exiting from the LED. The reflective planes are separated by an odd integral multiple of (» n /4) where » n is the wavelength of the light in the layer between the active region and the reflective contact, resulting in compensating interference maxima and minima, a more uniform distribution of light, and increased consistency in light output from LED to LED.
