The original version of this Article contained typographical errors.


Parts of Figure 1, 2, 3 and Figure 5 did not display correctly.


The original Figure 1, 2, 3 and Figure 5 and their accompanying legends appear below.

Figure 1

THz transmitters: (a) heterodyne transmitter, (b) proposed single-path THz transmitter with SSB-C optical modulation and DSB receiver. SSB-C: single sideband with carrier, DSB: double sideband, IF: intermediate frequency, SSBI: signal-signal beat interference.

Techniques for the generation of SSB-C signals: (a) IM SSB-C, and (b) field SSB-C; and techniques for the mitigation of the signal-signal beat interference (SSBI): (c) setting a guard band (GB) between carrier and sideband, and (d) iterative pre-distortion.

(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 fRF and fIF (calculations made with \(\beta_{2}\) =  − 21.7 ps2/km).

Additionally, equations 1, 18 and 19 contained an error, where “-β2” should read “β2”.
