Spontaneous emission spectra (in units of ) as a function of detuning frequency δ_k for different photonic band gap widths and positions. (a) δ_14c1 = 0.1, δ_14c2 = 0.15; (b) δ_14c1 = −0.1, δ_14c2 = 0.3; (c) δ_14c1 = −1.5, δ_14c2 = 1.6. The other parameters are set to be |Ω₁| = 0.5, Ω = 0.5, Ω₃ = 2, θ = 0.2π, A₁(0) = 0, A₂(0) = 1, and A₃(0) = 0.
