“…The LFM waveforms can also be generated based on the Fourier domain mode-locked optoelectronic oscillators (OEOs) [106]- [110]. Besides, investigations are also taken in the microwave photonic dual-chirp LFM signal generation [111]- [122] to avoid the range-Doppler coupling effect of the single-chirp LFM signal [123]- [125].…”

Cognitive radio is considered as a possible disruptive force to improve the spectral resource efficiency through sensing and interacting with the environment. Traditional electrical technologies to implement the cognitive radio face challenges in terms of bandwidth, resolution, and speed. In this paper, the concept and architecture of broadband cognitive radio systems enabled by photonics are proposed. Key microwave photonic techniques for the architecture are reviewed, including the photonics-based spectrum sensing, the photonic arbitrary waveform generation, the photonics-based self-interference cancellation processing, and the microwave photonic dechirp processing and radar imaging. A preliminary demonstration of a cognitive radar system enabled by photonics is performed. The future possible research directions on this topic are discussed.

“…Optical single sideband (OSSB) modulation is defined that one of the double sidebands (DSB) is remained and the other one is suppressed after lightwave being modulated by microwave. The anti-dispersion property of OSSB is significant to overcome the power fading effect in the dispersive radio over fiber (RoF) link, such as multistatic radar and 5G/6G wireless communication systems 1,2 . Additionally, the frequency shift of OSSB has been paid much attention in some frontier researches.…”

We demonstrate a single chip silicon-based optical single sideband (OSSB) modulator which is composed of a branch line coupler (BLC) and a silicon dual-parallel Mach-Zehnder modulator (DP-MZM). Benefit from the powerful tool of optical domain compensation we propose, the constrains such as power imbalance and phase offset of BLC are eliminated. As a result, we realize a fully functional OSSB chip to implement full carrier OSSB (FC-OSSB) and suppressed carrier OSSB (SC-OSSB) modulations. The maximum sideband suppression ratio (SSR) of 35 dB is derived at 21 GHz.

“…Photonic generation of dual-chirped waveform has been widely studied in recent years. The common methods include integrated optical modulator based methods, [15][16][17][18][19] cascading modulators based methods, [20][21][22][23] sweeping laser based methods, [24] and optically injected semiconductor laser based methods. [25,26] All methods mentioned above can only generate one kind of linearly chirped waveform, which cannot meet the requirements of multifunctional radar systems.…”

A switchable down-, up- and dual-chirped microwave waveform generation technique with improved time-bandwidth product (TBWP) is proposed and demonstrated based on a dual-polarization dual-parallel Mach-Zehnder modulator (DP-DPMZM) cascaded with a polarization modulator (PolM). By properly controlling the phase shifts of the radio frequency signals applied to the DP-DPMZM, switchable down-, up- and dual-chirped waveforms with simultaneous frequency and bandwidth doubling can be generated. To enlarge the TBWP further, splitting parabolic signal and phase-encoding splitting parabolic signal are used to drive the PolM for the enhancement of bandwidth and time duration. Numerical results demonstrate the generation of down-, up- and dual-chirped microwave waveform with TBWP of 8, 160 and 10240. The propose method may find applications in future multifunction radar systems due to the high performance and flexibility.
