The Journal of Photonics for Energy (JPE) invites original research, review articles, and perspectives in the field of photonics for neuromorphic computing and artificial intelligence (AI).

The computing power required by AI models is rapidly increasing, roughly doubling every three months. However, continuing to use conventional computing architectures is not sufficiently scalable given that the computing principles of AI models, which are highly parallel and distributed, with localized memory, are fundamentally different from those of conventional digital processors. The significant divergence between the two architectures slows down computation speed and increases power consumption.

Photonics has unmatched performance potential for interconnects in terms of bandwidth and power efficiency. As a result, photonic-enabled neuromorphic engineering promises sub-nanosecond latencies and high bandwidth with low energy, by leveraging massive high-bandwidth interconnect with co-integrated nonvolatile memories. To achieve high-speed and low-power neuromorphic photonic hardware that can outperform digital electronics, a wide range of technologies must work together, including materials, devices, hardware architecture design, fabrication and packaging technologies, methodologies for photonic device and circuit design and implementation, etc. Such integrated systems will then have potential use in a variety of unconventional computing paradigms that have been or are yet to be envisioned.

The purpose of this special section is to highlight recent advances and trends in the field of photonics for neuromorphic computing and AI. Potential topics include but are not limited to: 

  • Materials and devices: energy-efficient and high-speed materials and devices for weight programming and photonic nonlinearities, phase change materials for photonic memory, etc.
  • Novel computing architectures: feedforward, recurrent and convolutional neural networks, spiking neural networks, photonic reservoir computing, photonic Ising machines, and other unconventional computing approaches
  • Hardware platforms: integrated photonics, fibers, free-space optics, metasurfaces/devices, etc.
  • Photonic memories and photonic DACs
  • Training of neuromorphic photonic hardware
  • Photonic design (e.g., inverse design) and implementation methods for optical computing
  • Novel applications of neuromorphic photonic hardware

All submissions will be peer reviewed. Peer review will commence immediately upon manuscript submission, with a goal of making a first decision within six weeks of manuscript receipt. Submissions should follow the author guidelines for JPE. Manuscripts should be submitted online at A cover letter indicating that the submission is intended for this special section should be included.
