Real and imaginary part contributions to total diffraction efficiency. Contributions to diffraction efficiency by (a) real part Δε and (b) imaginary part Δε of the IPPC slab, independently. The blue dash-dot lines denote the real/imaginary part Δε. The black solid lines denote real/imaginary part contributions. The red dash lines denote total FODE calculated by using original εD and εP. The dash-dot-dot vertical line is the resonant absorption wavelength λ0 of doping agent.
