Visible and near infrared dispersion of figure of merit defined for a reconfigurable phase change nanophotonic medium (FOM $=\frac{{\mathbf{n}}_{\mathbf{a}}^{\Delta \mathrm{n}}}{{\mathbf{k}}_{\mathbf{c}}}$), where n_a is refractive index of amorphous phase and k_c extinction coefficient of the lossy crystalline phase
