Abstract
New light-emitting diodes (LED) structure constituted by the photonic crystal (PhC) is presented, and the effects of structure parameters are investigated. Relying on the results of investigation, the structure parameters of photonic crystal LED are optimized. By Using the FDTD algorithm, the enhancement factor of photonic crystal LED is calculated efficiently, and the optimum values of structure parameters are obtained after numerical optimization. With the optimum photonic crystal structure, the output efficiency of LED is enhanced.
