A general device simulator has been constructed for designing high-efficiency light-emitting diodes (LEDs). The optical characteristics, including the spatial profiles of the light extracted from LEDs, are important for practical LED applications such as display and illumination. The radiation patterns are affected by device structures such as electrodes, which determine the current distribution, and by the light-absorbing layers, which intercept the internal light emission. The simulator analyzes light extraction efficiency and the radiation pattern, both of which are very important in designing an optical system using LEDs. The simulator is useful for designing high-efficiency LEDs and package configurations for various applications.
