“…Phase-coded microwave or millimeter signals have wide applications in modern radar and communication systems. As a result of the extreme congestion of low-frequency bands of the RF spectrum, the operation frequency of phase-coded signal is developing toward high-frequency bands [1]. Conventionally, a phase-coded signal is generated in the electrical domain, but it suffers from limited operation bandwidth and small tunability due to the inherent electronic bottleneck.…”

A novel approach for photonic generation of a frequency-quadrupled phase-coded signal using optical carrier shifting and balanced detection is proposed and demonstrated. The key component of the scheme is an integrated dual-polarization quadrature phase shift-keying (DP-QPSK) modulator. In the modulator, an RF signal is applied to the upper QPSK modulator to generate high-order optical sidebands, while an electrical coding signal is applied to the bottom QPSK modulator to perform optical carrier phase shifting. After that, a frequency-quadrupled phase-coded signal with an exact π-phase shift is generated through balanced detection. The proposed scheme has a simple, compact structure and good tunability. Besides, a phase-coded pulse can be directly obtained when a three-level rectangular coding signal is applied. A proof-of-concept experiment is carried out. The generation of a 2-Gbit/s phase-coded signal with a frequency tuning from 12.12 to 28 GHz is experimentally demonstrated, and the generation of a phase-coded microwave pulse is also verified.

“…Ultrafast optical/microwave waveforms with a bandwidth up to tens/hundreds of Gigahertz could find applications in numerous fields, such as high speed optical communications, biomedical imaging, and coherent control in chemistry [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Photonics-assisted techniques have attracted much attentions thanks to their applications in many fields [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], such as microwave frequency measurement, analog-to-digital conversion, microwave photonics sensing, broad bandwidth radar and microwave photonics filter.…”

This paper reviews recent progresses on optical arbitrary waveform generation (AWG) techniques, which could be used to break the speed and bandwidth bottlenecks of electronics technologies for waveform generation. The main enabling techniques for optically generating optical and microwave waveforms are introduced and reviewed in this paper, such as wavelength-to-time mapping techniques, space-to-time mapping techniques, temporal pulse shaping (TPS) system, optoelectronics oscillator (OEO), programmable optical filters, optical differentiator and integrator and versatile electro-optic modulation implementations. The main advantages and challenges of these optical AWG techniques are also discussed.

“…6,7 The radar pulses, for example, are usually frequency chirped to improve the time-bandwidth product (compression ratio), thus to promote the range resolution under the same radar detection distance. Photonic generation methods, such as direct frequency-to-time mapping technique 8,9 and heterodyne-beating technique, 10,11 have been proposed and achieved. As a promising alternative, photonic generation of linear frequency-chirped signal can meet the requirements of high center frequency and broad chirp range.…”

We demonstrated a photonic approach to generate a phase-continuous frequency-linear-chirped millimeter-wave (mm-wave) signal with high linearity based on continuous-wave phase modulated optical frequency comb and cascaded interleavers. Through linearly sweeping the frequency of the radio frequency (RF) driving signal, high-order frequency-linear-chirped optical comb lines are generated and then extracted by the cascaded interleavers. By beating the filtered high-order comb lines, center frequency and chirp range multiplied linear-chirp microwave signals are generated. Frequency doubled and quadrupled linearchirp mm-wave signals of range 48.6 to 52.6 GHz and 97.2 to 105.2 GHz at chirp rates of 133.33 and 266.67 GHz∕s are demonstrated with the AE1st and AE2nd optical comb lines, respectively, while the RF driving signal is of chirp range 24.3 to 26.3 GHz and chirp time 30 ms.
