“…Broadband radio frequency (RF) arbitrary waveform generation (AWG) is of great significance in many applications, such as future 5G/6G RF systems for capacity increasing and noise removal, 1 ultra-band radar systems for speed and range resolution improvement, 2 quantum computing for quantum state evolution manipulation, 3 and nuclear magnetic resonance for molecular structure imaging 4 . However, limited by the relatively low sampling rate and conversion resolution of electronic digital-to-analog converters (DACs), it is difficult to achieve RF arbitrary waveforms with bandwidth higher than tens of GHz without degrading bit resolution using current commercial electronic AWGs 5 .…”

.Conventional temporal pulse shaping (TPS) for radio frequency (RF) arbitrary waveform generation (RF AWG) based on the Fourier transform relation between the input–output waveform pair requires the electronic AWG to generate RF input signal, which greatly limits the output waveform diversity due to the relative low sampling rate and bit resolution of electronic AWG, i.e., high-fidelity square waveforms are hard to be achieved since high-resolution broadband Sinc input signals are difficult to be generated by current commercial electronic AWGs. The approaches based on TPS with phase modulation incorporating with iterative algorithms can relatively improve the waveform diversity by applying the optimal phase information. However, time-consuming iterative algorithms significantly restrict the waveform reconfigurability, i.e., desired RF waveforms cannot be generated in real-time. We propose a novel high-stable and reconfigurable RF AWG scheme with multi-tone inputs, which aims to improve the output waveform diversity with simple manipulation and high stability. In our design, any desired RF waveform can be achieved in real-time by simply adjusting the power values of multi-tone inputs. A proof-of-concept experiment was implemented, which fully verified the feasibility of the approach. The system performance in terms of output waveform stability was investigated in detail. As no electronic AWG is employed and no iterative algorithms are required, the proposed design provides a promising solution for high-performance reconfigurable photonic-based RF arbitrary waveforms generation.

“…MPFs can be divided into coherent and incoherent filters [4]. They can find rich applications in various devices and sys tems, for example, sensors [7,8], optoelectronic oscillators (OEOs) [9], arbitrary microwave waveform generation and pulse compression [10], and multibeamforming [11] etc. The notch filter, which is a kind of coherent filter, is also an essential part in radar systems, broadband wireless networks, and satellite communications [12,13], because it can remove undesired interference signals in the systems [14].…”

The development of radiofrequency (RF) filters with bandwidth reconfigurability and frequency tunability in the MHz range is increasingly important to broadband wireless communication and radar systems. In this paper, we demonstrate a reconfigurable RF filter based on a silicon integrated optical true time delay line (OTTDL). The OTTDL is a four path parallel structure with the reconfiguration enabled by thermooptic Mach-Zehnder interferometer switches. By controlling the power splitting ratio of the switches, three different orders of finite impulse response filters with a variable bandwidth are realized. The bandwidth can be varied from 180.9 MHz to 662.0 MHz and the center frequency can be tuned in one freespectral range up to 1 GHz.

“…This method is simple in structure. Another typical method is based on the matched filters, which realized by spectral shaping and time mapping principle [11]- [13]. This method can be reconfigurated flexibly by operating the spectrum of the broadband optical source (BOS) via a spectral shaper.…”

A Chirp-Rate-Tunable Microwave Photonic Pulse Compression System for Multi-Octave Linearly Chirped Microwave Waveform

A chirp-rate-tunable microwave photonic pulse compression system for multioctave linearly chirped microwave waveform (LCMW) is proposed in this paper. The key components are a dual-parallel Mach-Zehnder modulator (DPMZM) and a dispersive loop (DL) structure based on a linear chirped fiber Bragg grating. By controlling the output of the DL to change the accumulated group velocity dispersion, the chirp rate of the system can be tuned. By adjusting the wavelength of the optical carrier to select the single sideband modulated optical signal (positive or negative sideband), the chirp direction (down or up chirped) can also be tuned. The performance of the multi-octave LCMW pulse compression can be improved by eliminating the second-order harmonic distortion through configuring the bias voltages of the DPMZM. Detailed theoretical analysis is conducted. A verification simulation demonstrates the pulse compression of the multi-octave LCMWs with the chirp rates of 23.877, 11.939, 3.979, and -3.979 GHz/ns. In the proof-of-concept experiment, the matched chirp rates 23. 229, 12.051, -22.568, and -11.355 GHz/ns are obtained. The multi-octave LCMW pulse compressions with the compression ratios of 14.3, 29.3, 15.0, and 28.6 are verified. The simulation and experiment results are in good agreement with the theoretical analysis.
