Integrated Photonics: Progress, Challenges, and Future Prospects

Dear Colleagues,

Integrated photonics represents a revolutionary approach to optical systems by enabling the generation, transmission, and manipulation of light signals within miniature chips. This technology achieves the high-density integration of complex optical components on a single substrate, significantly enhancing system stability, integration density, and energy efficiency. Over the past decade, substantial breakthroughs have been made across the entire technological chain—from fundamental materials to system architecture—while key challenges in manufacturing processes, heterogeneous integration, and power consumption control remain to be addressed in the industrialization journey.

This Special Issue will focus on innovative breakthroughs and systematic solutions in integrated photonics, covering, but not limited to, the following research areas:

• Silicon photonics and heterogeneous integration platforms;
• Photonic integrated circuit design and simulation;
• Low-loss optical waveguides and resonators;
• Programmable photonic processors;
• Microwave photonics and quantum photonic chips;
• On-chip lasers and photoelectric co-design;
• Advanced packaging and testing technologies;
• Neuromorphic photonic computing;
• Biomedical sensing applications;
• Data center optical interconnection technologies.

We invite scholars in related fields to contribute research articles, reviews, and perspectives to collectively advance integrated photonic technologies toward new developmental stages.

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 250 words) can be sent to the Editorial Office for assessment.

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.
