“…The applied electrical voltage is 2.707 V, and the modulation efficiency is about 0.0195 mW/V in our scheme. Compared with the two octupling mm-wave generation schemes in [14] and [22], whose applied electrical voltages and modulation efficiencies are 3.827 V, 0.0550 mW/V and 4.862 V, 0.2616 mW/V respectively, the efficiency of our scheme is lower, but the electrical voltage needed is much lower too. The low efficiency can be compensated by optical amplification, and in fact, all the three methods need amplification to achieve a certain power to be transmitted to the base station.…”

“…Recently, many methods have been developed to generate mm-wave signal in optical domain. In [14], a method to generate optical mm-wave with eightfold frequency of the local oscillator with a nested MZM is proposed. In [15], three techniques to generate mm-wave have been comprehensively investigated using a MZM and an optical bandpass filter, which is used to suppress undesired optical harmonics.…”

Abstract:In this work, we investigate the influence of the second order-(2OD) and third order-(3OD) dispersion terms on chirp signal generation and transmission through RF photonic link without optical filter. Dispersion equations are formalised using Taylor series and Bessel function to study the link performance. Our result (Eye diagrams) shows that the 2OD+3OD have significant impact on chirp mm-wave propagating through fiber of different lengths. In this paper chirp mm signal is controlled at photo detector by individual phase term of external modulators. Moreover, we also demonstrated experimentally that the chirp rate can be significantly controlled by properly choosing the type of fiber in the experiments. We discussed the RF photonic link performance in terms of Optical Sideband Suppression Ratio (OPSSR), Radio Frequency Spurious Suppression Ratio (RFSSR), Bit Error Rate (BER).Theoretical results are verified using MATLAB Software.2

“…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.
