Description
In this work, we calculate the local density of states using dyadic Green's functions for a defective one-dimensional photonic crystal of finite size composed of polymeric layers. The spatial periodicity of the crystal is broken when infiltrating a cavity to detect a cancer cell. This work considers that the refractive index of polymeric materials changes with the applied pressure. We determined the existence of a confined mode within the cavity with a maximum value of the local density of states. The results show that, as pressure increases, the local density of states decreases within the confined mode.
