Advances in Integrated Photonics: From Materials to Devices and Systems

Dear Colleagues,

Integrated photonics is important and essential for photonic applications. Similar to integrated electronics, the integration technique can not only significantly reduce the sizes of optical systems, improving their robustness as a result, but also makes low-cost mass production impossible, which may bring about a revolution in both fundamental research and practical applications regarding photonics. In this area, plenty of exciting achievements have been reached in recent years, ranging from the low-loss and high-accuracy fabrication of various substrate materials, including III–V semiconductors, silicon, silica, silicon nitride, lithium niobate, aluminum nitride, polymers, metal optics, etc., to high-performance integrated photonic devices with both passive (modulators, switches, filters, etc.) and active (lasers, amplifier, detectors, etc.) aspects. With these constituent materials and building blocks, compact and cost-effective integrated optical systems can be created, resulting in breakthroughs in sensing, computation, and communication technologies and in many other areas in both classical and quantum scenarios, thereby helping to revolutionize photonics.

The aim of this Special Issue is to present recent the advances in the diverse aspects of integrated photonics, from materials to devices and systems.

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.
