Special Issue Information

Dear Colleagues,

We are delighted to welcome you to submit your work for this Special Issue of Crystal on “Advanced Research of Silicon Photonics and Optoelectronics Devices”.

Silicon Photonics has finally been able to achieve a wide diffusion, making it one of the major technologies of the future. Several products have hit the market in many fields, from communication devices to interconnect, optical computing, sensors, and biosensors. However, many challenges are still holding back Silicon Photonics from expressing its full potential: laser integration, component density, power consumption, limited bandwidth, non-linearities, and integration are among those challenges. Research in this field has never stopped proposing new solutions, such as looking for new materials, novel devices and circuits, and new architectures that leverage the potential of working with photons. With this Special Issue on Advanced Research of Silicon Photonics and Optoelectronics Devices, we want to share and highlight the most recent results for Silicon Photonics and Optoelectronic devices, ranging from designs, fabrication, and experimental demonstrations. Original research work, letters, and review papers based on theoretical, numerical, and experimental data are welcome in this Special Issue.

The topics of interest include, but are not limited to, the following:

  • Silicon Photonics
  • Photonic integrated circuits
  • Optoelectronic devices
  • Advanced materials for photonics and optoelectronic devices
  • Communications and interconnect
  • Optical computing
  • Free-space communications
  • Photonic integration and packaging
  • High-density photonic circuits

We look forward to receiving your proposal!

Over the last two decades, time- and angle-resolved photoemission spectroscopy (trARPES) has become a mature and established experimental technique for the study of ultrafast electronic and structural dynamics in materials. To date, most trARPES investigations have focused on the investigation of processes occurring on time scales of ≳30 fs, in particular, relaxation and thermalization, and have therefore been blind to the initial sub-10 fs dynamics related to electronic coherence and correlation effects. In this article, we illustrate how current trARPES setups reach their limits when it comes to addressing such extraordinarily short time scales and present an experimental configuration that provides the time, energy, and momentum resolutions required to monitor few-femtosecond dynamics on the relevant energy and momentum scales. We discuss the potential capabilities of such an experiment to study the electronic response of materials in the strong-field interaction regime at PHz frequencies and finally review a theoretical concept that may in the future even overcome the competing resolution limitations of trARPES experiments, as imposed by the time–bandwidth product of the probing laser pulse. Our roadmap for ultrafast trARPES indicates a path to break new experimental ground in quantum nonequilibrium electronic dynamics, from which new possibilities for ultrafast control of optical and electronic signals in quantum materials can be explored.
