From: Diffractive properties of imaginary-part photonic crystal slab
Real and imaginary part contributions to total diffraction efficiency. Contributions to diffraction efficiency by (a) real partΔ ε and (b) imaginary partΔ ε of the IPPC slab, independently. The blue dash-dot lines denote the real/imaginary partΔ ε . The black solid lines denote real/imaginary part contributions. The red dash lines denote total FODE calculated by using originalεDandεP. The dash-dot-dot vertical line is the resonant absorption wavelengthλ0of doping agent.
