(a) Dispersion-induced phase shifts in each of the signals generated in a single-path photonic system with DSB demodulation, \(\varphi_{S + 1} ,\,\,\varphi_{C + 1} ,\,\,\varphi_{S - 1} ,\,\,{\text{and}}\,\,\varphi_{C - 1}\) are the phase shifts due to chromatic dispersion of the carriers and sidebands of the two SSB-C optical signals (all phases are relative to that of the pulse center, which has a frequency of f₀); (b) DSB demodulation receiver; (c) SSB demodulation receiver; and (d) downconverted sideband power gain versus length of the optical fiber link for the SSB and DSB receivers and various values of f_RF and f_IF (calculations made with \(\beta_{2}\) =  − 21.7 ps²/km).
