“…Even when ER is within the practical limit of 30 dB, the measured OSSR and RFSSR are 28 dB and 48 dB respectively and thus ensures filterless generated of the MM-Waves. When the practical values of ERs are considered, the OSSR and RFSSR are 4 dB and 30 dB higher than reported in [14] and 6.5 dB and 10 dB higher than reported in [15] when the practical limits of the ER is considered. If high ER In practice it is difficult to keep the input power of both the arms perfectly matched, hence the power imbalance between upper and lower arms are simulated and analysed.…”

“…However, uncontrolled optical sideband resulted low OSSR and RFSSR of 24 dB and 18 dB respectively. A cascaded combination of two DP-MZM based 16-tupling [15] offered 21.5 dB of OSSR and 38 dB of RFSSR. The uncontrolled optical and electrical sidebands affected the purity of the generated MM-Wave signals and the suppression ratios are sensitive to the MI.…”

“…The higher modulation indices will have low conversion efficiency. Moreover, RFSSR and OSSRs of the proposals [19][20][21] are low. Hence in this paper, a cascaded combination of four MZMs is utilized to reduce the modulation index and improve the optical and RF sideband suppression ratios.…”

“…Hasan et al have utilized array of four phase modulators to generate frequency octupling and 24 tupling [18]. Recently, several frequency 16-tupling techniques have been demonstrated using two cascaded MZMs with two tunable lasers [19], dual parallel MZMs [20], two cascaded dual parallel MZMs [21], and dual stage cascaded MZMs [22]. The modulation indices of these schemes are very high and used complex circuit arrangements.…”

Background: An optical Millimeter Wave (MM-Wave) generation with high frequency multiplication factor is very attractive solution to avoid the use of high frequency local oscillators at the central station. Results: The cascaded structure has resulted very low modulation index of 2.827 and 54 dB and 42 dB of OSSR and RFSSR respectively. Analysis of both optical and RF sided band suppression ratios under non-ideal cases are also simulated and presented. Further, 10 Gbps NRZ data transmission performance over 50 km Single Mode Fiber (SMF) is also evaluated. Conclusions: The proposed structure can tolerate up to few degrees of non-ideal parameter variation and is very simple to realize.

“…Among these, external modulation based frequency multiplication techniques have become popular due to higher modulation bandwidth, tunability and high stability [2,3]. Several multiplication techniques have been proposed with different multiplication factors such as doubling [3], tripling [4], quadrupling [5][6][7], sextupling [8], octupling [9], 12-tupling [10], 16-tupling [11,12] and so on. A MM-Wave generation technique with highest frequency multiplication factor reduces the need of high frequency RF local oscillator at the CS.…”

In this paper for the first time, a 60 GHz bidirectional Millimeter Wave (MM-Wave) Radio over Fiber (RoF) transmission through a new frequency dual 16-tupling of 3.75 GHz local oscillator (LO) is demonstrated. The proposed system is constructed with parallel combination of two cascaded stages of MZMs. The upper cascaded stage and the Lower cascaded stages are biased at the Maximum Transmission Point (MATP). By suitable adjustments of LO phase and amplitude, optical sidebands with spacing of 8 times the input LO frequency is generated. These sidebands are then separated using filters to achieve dual 16-tupling. A good agreement between numerical derivations and the simulation results are achieved. Further, a simulation is performed to access the dual bidirectional transmission performance for the double and single tone modulation with 2.5 Gbps data transmission. The transmission distance is limited to 25 km for the double tone modulation due to bit walk of effect. A 60 km link distance is achieved with single tone modulation. The dispersion induced power penalties less than 0. 5 dB at 10 −9 BER is observed for both up and down streams.
