Figure 2

Measured reflectance spectrum of SBRs with a different number of layers, (a) \({n}_{l}=10\) and (d) \({n}_{l}=6\), at the core of the structure. Calculated dipolar spontaneous emission decay rate \(\gamma \) for the transversal electric (b) and (e) and transversal magnetic (c) and (f) polarizations. In both geometries, the SBR band gap's center is fixed at \({f}_{B}=25 \; \mathrm{GHz},\) and the core radius is \({r}_{core}={\lambda }_{B}/4{n}_{air}\).
