Silicon nanocrystal-based photonic crystal slabs with broadband and efficient directional light emission
Original language description
Light extraction from a planar layer can be increased by introducing 2D periodic pattern on its surface. Photonic crystal (PhC) slab enhances the extraction efficiency of light and direct the extracted emission into desired angles. Careful design of the structures is important in order to have a spectral overlap of the emission with leaky modes. We show that by fabricating PhC slabs with optimized dimensions from silicon nanocrystals (SiNCs) active layers, the extraction efficiency of vertical light emission from SiNCs can be enhanced 11 times compared to that of uncorrugated SiNCs-rich layer. Increased light emission can be obtained in a broad spectral range and the extracted light can stay confined within relatively narrow angle around the normal to the sample plane. We demonstrate experimentally and theoretically that the physical origin of the enhancement is such that light originating from SiNCs first couples to leaky modes and is then efficiently extracted into the surrounding.n
