Frequency-Resolved Reciprocal-Space Mapping of Visible Spontaneous Emission f…

One of the original dreams of three-dimensional (3D) dielectric photonic crystals has been to provide a 3D “designer electromagnetic vacuum”, which would allow tailoring of the spontaneous emission from emitters such as two-level systems, atoms,molecules, defects, or quantum dots located inside this artifi cial environment. This idea opens a wealth of opportunities. [ 1–3 ] For example, i…
