Next-Generation Vertical-Cavity Surface-Emitting Lasers

Dear Colleagues,

Vertical-cavity surface-emitting lasers (VCSELs) have become light sources of great importance for industrial, sensing and consumer applications. They offer many inherent advantages, such as efficient high-speed modulation at low currents, superior fiber coupling efficiency, wafer-level fabrication and scalability in high-density array architectures.

At present, the growing bandwidth demands for data communication and new applications under research, including autonomous vehicle systems (LiDAR in particular), gas detection, biomedical sensing, imaging, quantum computing, chip-scale atomic devices, etc., drive the significant development of VCSEL technology. Novel trends and concepts in the design, configuration and fabrication of VCSELs emerge to meet the specification requirements of the next generation of photonic systems.

This Special Issue aims to present recent progress and original state-of-the-art research dealing with the advanced design, fabrication, characterization and application of various types of VCSELs. In this Special Issue, original research articles and reviews are welcome. We are pleased to invite you to submit your contribution to this Special Issue. Research areas may include (but are not limited to) the following:

• High power VCSELs;
• High-speed VCSELs;
• Tunable VCSELs;
• VCSELs based on new material systems;
• Novel VCSEL structure;
• Optical mode control in VCSELs;
• VCSEL-based communication;
• Characterization methods;
• Novel applications.

We look forward to receiving your contributions.

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.
