“…Optical locking techniques include the optical phase-locked loop (OPLL) and optical injection locking [ 17 , 18 ]. Optical frequency multiplication is classified into two categories: direct modulation [ 19 ] and external modulation [ [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] ]. The generated signals from a single light source have low phase noise, outstanding frequency stability, and are cost-effective.…”

“…At present, the main methods for generating optical mm-waves are based on the direct modulator, remote heterodyning, the external intensity modulator, four-wave mixing (FWM), and Brillouin scattering [6][7][8][9][10]. Among them, the method of using the external intensity modulator based on the principle of frequency multiplication to generate mmwaves of frequency multiplication light, which features high stability and low cost, is a hot research topic at home and abroad [10][11][12][13][14][15][16]. In one study [11], an arbitrary frequency multiplying signal was generated based on a single MZM and an optical wavelength selection switches (WSS) scheme.…”

“…However, the scheme was only studied as a double frequency system, and the signal rate was small, while the frequency of the generated signal was very small. Lu et al [16] theoretically proposed an optical mm-wave generation scheme based on frequency quadrupling and sextupling techniques. The scheme employs a single electrode modulator and is capable of filtering out the center carrier by adjusting the modulation index.…”

In order to reduce the number of devices in and cost of a multifrequency vector millimeter-wave (mm-wave) signal generation system, we propose a novel scheme for multifrequency vector mm-wave signal generation based on one dual-arm Mach-Zehnder modulator (MZM) without optical filtering. This scheme utilizes the carrier suppression modulation of a single modulator, without the need for optical filtering and combines precoding technology to generate high-frequency QPSK and 16 QAM mm-wave signals. The transmitter is applied with precoding technology to make the frequency multiplying vector mm-wave signal display regular vector modulation at the receiver, and the system is optimized with a phase factor to ensure that the phase distribution of QPSK signal at the receiver is symmetrical. We demonstrated the generation of 4-Gbaud 76 GHz QPSK and 16 QAM vector mm-wave signals through simulation. The simulation results show that, at a fiber transmission distance of 12 km, when the launched optical power of the PD is greater than −20.535 dBm, the bit error ratio (BER) of the QPSK signal is lower than the hard-decision forward error correction (HD-FEC) threshold of 3.8 × 10−3. At a fiber transmission distance of 10 km, when the launched optical power of the PD is greater than −18.637 dBm, the BER of 16 QAM signal is also lower than 3.8 × 10−3.

“…Mm-wave signal generation based on external modulation technology can be combined with frequency multiplication technology to realize mm-wave signal generation by low RF signal. Frequency doubling [24], tripling [25], quadrupling [26]- [29], sextupling [30], [31], octupling [32], [33], and even nonupling [34], [35] have been achieved based on external phase or intensity modulator. However, in order to attain electrical QPSK/QAM vector mm-wave signal, the RF vector signal need to be phase and/or amplitude pre-coded before driving the phase or intensity modulator.…”

In this paper, we propose a novel quadrature phase-shift keying (QPSK) vector millimeter-wave (mm-wave) signal generation based on odd times of frequency without precoding. The radio frequency (RF) vector signal generation module is universal for the generation of millimeter-wave signal with any odd frequency multiplication. Instead of phase precoding, the phases of electrical mm-wave signal are multiplied by the frequency multiplication number at the receiver after carrier phase estimation. The frequency tripling, quintupling, and septupling schemes are achieved by simulation, and bit-error-ratio curves demonstrate that the proposed QPSK vector mm-wave signal generation scheme works well.
