Abstract :
We integrated two-dimensional photonic crystal patterns with triangular lattice of air holes in the amorphous Si/Si3N4 multilayer stack to compensate for the poor internal brightness. The significant light extraction enhancement can be observed in the third direction, implying the spontaneous emission band strongly coupling with the resonant radiation band or leaky conduction band modes of the photonic crystal slabs at Gamma point in the photonic band structures.
