The two dimensional photonic crystal slab with designated defects, namely H1, H2, and L3 type cavities, are investigated aiming at achieving more efficient light extraction. By using the finite–difference time–domain method, effects of finite air-hole radius and depth, and the thickness of cladding layer on the light extraction efficiency are examined. For the selected Gallium Nitrogen blue light emitting LED, values of radius, depth, thickness, that achieved improved photoluminescence, are identified.
