Figure 5From: On the generalized Hartman effect presumption in semiconductors and photonic structuresThe phase times τ n as functions of the reduced thicknesses. The phase times τ n as functions of the reduced thicknesses a/λ (a) and b/λ (b) for a superlattice (L/H/L)n made of fused silica (L) (n L =1.41) and titanium oxide (H) (n H =2.22) for λ=702 nm.The oscillating behavior of τ n with clear band structure is far away of any Hartman effect.Back to article page
