Emission rate enhancement in a band gap structure

We investigate the resonant enhancement of transmission and reflection of a plane electromagnetic wave incident on a multilayer three-dimensional fully dielectric photonic crystal in which a defect layer with excited medium inclusions has been designed specifically to obtain a high-density mode. The numerical investigation is performed for a near infrared wavelength range. Comparison of transmission and reflection coefficient values for structures with different thicknesses of a defect layer and values of an imaginary part of an active medium permittivity is presented.
