Highly Directional Emission and Photon Beaming from Nanocrystal Quantum Dots Embedded in Metallic Nanoslit Arrays

We demonstrate a directional beaming of photons emitted from nanocrystal quantum dots that are embedded in a subwavelength metallic nanoslit array with a divergence angle of less than 4°. We show that the eigenmodes of the structure result in localized electromagnetic field enhancements at the Bragg...
