“…In the literature, [18] a 32-fold millimeter-wave signal is realized, but up to eight modulators are used. There are many uncertain factors in the circuit transmission process, it is difficult to realize the control of the circuit devices, which greatly increases the complexity of the system; currently, the MZM technology to generate millimeter wave with low multiplication factor is becoming more and more mature, but there are still some problems to be solved in the generation of millimeter wave with high multiplication factor, [19][20][21] such as OSSR and the improvement of the RFSSR, the simplification of the system structure, etc.…”

This paper proposes a 32‐tupling frequency millimeter‐wave (MMW) filter‐free system based on four Mach‐Zehnder Modulators (MZM) connected in parallel and cascaded with a simple radio‐fiber (RoF) link structure. The four MZMs are all at the maximum transmission point (MATP), and the radio frequency (RF) driving voltage phase difference between MZMs is π /2. The center carrier is suppressed by using an optical attenuator (OATT) and an optical phase shifter (OPS). Two parallel MZMs can generate ±8th order and ±12th order optical sidebands, and the ±4th order optical sidebands can be suppressed by adjusting the modulation index m of the MZM, using cascaded two dual‐parallel MZMS(DPMZM) and the phase difference of the RF signal source is π/4 to generate ±16th order optical sidebands. The theoretical analysis and simulation experiments are performed for the scheme proposed in this paper. The results show that the simulated and theoretical values of the optical sideband suppression ratio (OSSR) for ±16th order optical sideband signals are 60.02 and 59.96 dB, respectively, and the simulated and theoretical values of the RF sideband suppression ratio (RFSSR) for the 32‐tupling MMW signal are 56.34 and 53.94 dB, respectively.

“…It is the most commonly used and proven method and has been widely exploited. Using external modulator methods, frequency doubling [ 17 , 18 ], quadrupling [ 19 ], octupling [ 20 ], 12-tupling [ 21 ], 16-tupling [ 22 ], 24-tupling [ 23 ], 32-tupling [ 24 , 25 ], optical MMW could be obtained.…”
