Special Issue Information

Dear Colleagues, 

Microwave photonics, as an interdisciplinary area, studies the interaction between microwave and optical signals to achieve to generate, process, control, and transmit microwave signals, taking advantages of high frequency, large bandwidth and low loss offered by modern photonics. In the past few years, microwave photonics techniques have been proposed and demonstrated for applications of broadband wireless access networks, sensor networks, radar, instrumentation, warfare systems and so on. However, there are still some challenges to be addressed. We are pleased to invite you to submit original research on the recent advances in microwave photonics technologies. 

This Special Issue aims to bring original research articles and reviews in order to contribute to the developments and applications of microwave photonics techniques.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Microwave photonic filters;
  • Optoelectronic oscillators;
  • Optical frequency combs;
  • Photonic generation and processing of microwave and mm-wave signals;
  • Photonic true-time delay beamforming for phased array antennas;
  • Photonic analog-to-digital conversion;
  • Integrated microwave photonics;
  • Microwave photonic systems for sensing and communication applications;
  • Microwave photonics for radio frequency and microwave systems;
  • Novel devices and systems for microwave photonics;
  • Novel applications of microwave photonics. 

We look forward to receiving your contributions.

A scheme of a photonic convolution processor based on a tunable electro-optic frequency comb is proposed. The optical frequency comb (OFC) is generated using a dual-parallel Mach–Zehnder modulator (DPMZM) driven by an RF signal. By adjusting the working parameters of the DPMZM, OFCs with different line number and frequency spacing can be produced to reconfigure the convolution kernel dimensions. A linearly chirped fiber Bragg grating (LCFBG) is employed to implement interleaving of temporal and spectral dimensions. The interleaved signals are sampled at specific time and summed after optoelectronic conversion, and the convolution operation is completed. In this work, using a 10 GHz RF signal, a 4-line OFC with a frequency spacing of 20 GHz and a 2-line OFC with a spacing of 40 GHz are generated to obtain a 2 × 2 and 1 × 2 convolution kernels, respectively. The convolution results are fed into an electronic pooling layer and a fully connected layer for classifying the images of the MNIST handwritten digit dataset. The results demonstrate that a classification accuracy of 95.7% is achieved using the 2 × 2 convolution kernel, and a higher classification accuracy of 96.5% is obtained with the 1 × 2 convolution kernel.
