Probe absorption-gain spectra: (a) \(R_{n0} = 1\) meV, \(\phi _1 = \phi _2 = 0\); (b) \(R_{n0} = 2\) meV, \(\phi _1 = \phi _2 = 0\); c(i). \(R_{n0} = 4\) meV, \(\phi _1 = \phi _2 = 0\); d(i) \(R_{n0} = 3\) meV, \(\phi _1 = \phi _2 =\pi /2\). c(ii) [d(ii)], c(iii) [d(iii)], and c(iv) [d(iv)] show the respective contribution of \(T_L, T_{NL1}\), and \(T_{NL2}\) to the formation of spectrum shown in Fig. c(i) [d(i)]. Parameters: \(\phi = \pi /2, R_{na} = R_c = 10\) meV, \(R_m = 0.05\) meV, \(\Delta _p = 30\) meV, \(\Delta _c = -10\) meV, and \(\Delta _m = 12\) meV.
