Special Issue Information

Dear Colleagues,

Designing integrated photonic systems presents a significant challenge, encompassing not only the precise solution of electromagnetic equations but also the integration of material and quantum physics equations to facilitate the examination and assessment of near-field interactions. These investigations must seamlessly align with the processes of device fabrication and characterization, with the purposes of validating device concepts and enhancing device designs. Optical communication networks have become a vital component of both national and international telecommunications infrastructure. Researchers have explored and developed intelligent and advanced optical signal processing methods to mitigate transmission distortions in optical links and transceivers. This Special Issue is dedicated to collecting original research and review articles that focus on recent advancements, technologies, and innovative applications in the field of nanophotonic techniques within optical communication systems, networks, and signal processing.

Potential topics include but are not limited to:

  • Nanophononics in communication systems;
  • Optical communication systems and networks;
  • Signal processing and machine learning technologies;
  • Distributed and lumped optical amplifications;
  • Linear and nonlinear on-chip devices.

On-chip optical modulators, which are capable of converting electrical signals into optical signals, constitute the foundational components of photonic devices. Photonics modulators exhibiting high modulation efficiency and low insertion loss are highly sought after in numerous critical applications, such as optical phase steering, optical coherent imaging, and optical computing. This paper introduces a novel accumulation-type vertical modulator structure based on a silicon photonics platform. By incorporating a high-K dielectric layer of ZrO2, we have observed an increase in modulation efficiency while maintaining relatively low levels of modulation loss. Through meticulous study and optimization, the simulation results of the final device structure demonstrate a modulation efficiency of 0.16 V·cm, with a mere efficiency–loss product of 8.24 dB·V.
