Bistable behavior of reflection and transmission of a one-dimensional photonic crystal with a dense resonant medium as a defect

We consider the optical response of a one-dimensional photonic crystal with a dense resonant medium as a defect. Using the iteration matrix approach, we calculate the intensity distribution in this structure and the reflection and transmission properties of it. We discuss the influence of photonic crystal on the bistable behavior of a dense resonant medium both within and outside the region of intrinsic optical bistability. Finally we compare our results with the case without taking into account near dipole-dipole interaction.
