“…Compared with the conventional electrical method, the optical method is preferable [15][16][17]. By beating the two high-order optical sidebands with good coherence in a square-law photodetector (PD), a laser with an optical external phase or intensity modulator is a promising and attractive technology for the generation of high-frequency mm-wave signals, the frequency of which can be several-folds that of the radio frequency (RF) local oscillator [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. In this technology, a high optical sideband suppression ratio (OSSR) is extremely desirable for the generation of high-quality mm-wave signals.…”

Abstract-In this paper, we propose a new approach to generate quadrupling-frequency optical millimeter-wave (mm-wave) signal with carrier suppression by using two parallel Mach-Zehnder modulators (MZMs) in Radio-over-fiber (RoF) system. Among the numerous properties of this approach, the most important is that a filterless optical mm-wave at 60 GHz with an optical sideband suppression ratio (OSSR) as high as 40 dB can be obtained when the extinction ratio of the MZM is 25 dB. Simplicity and cost-effectiveness have made this approach a compelling candidate for future wave-division-multiplexing RoF systems.Theoretical analysis is conducted to suppress the undesired optical sidebands for the high-quality generation of frequency quadrupling mm-wave signal. The simulation results show that a 60 GHz mm-wave is generated from a 15 GHz radio frequency (RF) oscillator with an OSSR as high as 40 dB and an radio frequency spurious suppression ratio (RFSSR) exceeding 35 dB without any optical or electrical filter when the extinction ratio of the MZM is 25 dB. Furthermore, the effect of the non-ideal RF-driven voltage as well as the phase difference of RF-driven signals applied to the two MZMs on OSSR and RFSSR is discussed and analyzed. Finally, we establish a RoF system through simulation to verify the transmission performance of the proposed scheme. The Q-factor performance and eye patterns are given.

“…Moreover, Equation (18) shows that the amplitude of the current for the desired MMW signal at 4w RF is independent of fiber dispersion. Therefore, the desired MMW signal is free from the drawback of the power fading induced by fiber dispersion.…”

“…The optical method is preferable over the conventional electrical method [13,14]. Various techniques have been developed, such as the stimulated Brillouin scattering (SBS) in optical fiber [15], the use of four-wave mixing in a highly nonlinear fiber (HNLF) [16], and the optical frequency up-conversion using an external modulator, such as LiNbO 3 MZM [17][18][19][20][21][22][23][24][25][26][27]. Compared with these techniques, the optical frequency up-conversion technique could easily generate a stable MMW signal, because of good coherence of two or three generated optical sidebands.…”

Abstract-In this paper, we present a cost effective method to generate a high-quality quadruple frequency optical millimeterwave (MMW) signal using an integrated dual-parallel Mach-Zehnder modulator (IDP-MZM). Not only does the method minimize the complication of the central station (CS) and its frequency demand for the devices, but the generated optical MMW signal as well has good transmission performance. By properly adjusting the direct current (DC) bias, modulation index, and using two radio frequency (RF) driving signals with 135 • phase delay, a high quality dual tone optical MMW at 60 GHz is generated from a 15 GHz RF local oscillator (LO) with optical sideband suppression ratio (OSSR) as high as 32 dB and radio frequency spurious suppression ratio (RFSSR) exceeding 33 dB without optical filter when an IDP-MZM with 30 dB extinction ratio is utilized. Furthermore, the influences of a number of non-ideal parameters, such as imperfect extinction ratio, non-ideal RF driven voltage, and phase difference of RF-driven signals applied to two subMZMs of the IDP-MZM, on OSSR are studied through simulation. Finally, we build a Radio over Fiber system through simulation, and the transmission performance of the generated optical MMW signal is

“…With the fabrication constraints almost gone, circuits at millimeter and submillimeter frequencies are becoming the main topic for many scientists. Factors such as size reduction, higher data rate transmissions, increased security of communications or high spatial resolution play a decisive role in applications oriented toward imaging, medicine, satellite communications, security and defense [1][2][3][4][5][6][7][8][9][10].…”

In this work, a subharmonic frequency mixer for millimeter wave applications has been designed. The mixing and multiplication phenomena are simultaneously achieved via a nonlinear component consisting in a microstrip line gap covered by a graphene film coating. The circuit structure is made up of various filters, which have been optimized to ensure high port-to-port isolation. The nonlinear behavior of the subharmonic frequency mixer has been experimentally evaluated within the 39-40.5 GHz RF frequency band. The frequency downconversion is achieved by mixing the RF signal with the second harmonic component of a 17.9 GHz LO signal. Conversion losses are minimized by generating a return path for IF, through the use of a quarter wavelength open-ended stub.
