Special Issue Information

Dear Colleagues,

Optical 3D integration is becoming a growing trend in photonic integrated circuits, similar to what we have observed in electronic integrated circuit development. It not only offers high degrees of integration but also bringing new functionalities to microsystems. Combining with nanoelectronics, 3D integrated photonics would enable novel applications in sensing, high-performance computing, light detection and ranging (LiDAR), artificial intelligence, etc.

In this special issue, we will discuss emerging technologies and applications in optical 3D integration. We welcome you to submit your work in form of reviews, articles and communications. Topics of interest include but are not limited to:

  • Multilayer stacked photonic integrated circuits;
  • 3D arbitrary photonics by ultrafast laser inscription;
  • 3D printing for photonic integration;
  • Novel fabrication process for optical 3D integration;
  • Advanced 3D packaging techniques for electronic-photonic integration;
  • Novel applications enabled by 3D electronic-photonic integrated circuits;

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Photonics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In recent years, using silicon-based waveguide grating antennas in optical phased array has become a research focus. To date, this technique has not been widely implemented in practical applications. In this paper, the basic principle of a waveguide grating antenna is described, and the researches on effective length, uniform emission and the directionality of diffraction are summarized. Through analysis, it is found that there is a trend to prepare grating antennas by using a SiN/Si hybrid integrated platform. A novel design of grating antenna using the hybrid integration technique is proposed. It is convenient to match with the antenna front-end components on the structural level and is more practical.
