Semiconductor Lasers: Innovations, Challenges, and Future Perspectives

Dear Colleagues,

As one of the most commonly used coherent light sources today, semiconductor lasers are essential components in many optical systems, such as for optical communication, storage, sensing, and metrological applications, mainly as parts of photonic integrated systems. They can be linear Fabry-Pérot or ring-type lasers, operating in narrow linewidth, tunability, single frequency, multiple frequency, or pulsed. Their numerous applications are ever-increasing due to the unprecedented fabrication accuracy offered by photonic-integration technology, allowing total phase and intensity control of the generated laser light.

In such a well-defined embedded setting, the issues of reproducibility and long-term dynamic stability are becoming increasingly important and should be taken into account in the design and fabrication of such laser systems. Since precise control of the relevant parameters, such as cavity length, Bragg grating, and group velocities, is well feasible, knowledge of the dynamical behavior of semiconductor lasers in their dependence on parameter values can successfully be applied to optimal design.

This Special Issue aims at presenting original state-of-the-art research articles dealing with the dynamics and stability of semiconductor lasers in a broad sense, with special emphasis on their operation in a photonic integrated chip. Specifically, papers are solicited dealing with semiconductor lasers coupled to various kinds of external optical perturbations, such as delayed feedback, delayed coupling, optical injection, photonic nerve signal injection, etc. Researchers are invited to submit their contributions to this Special Issue. Topics include, but are not limited to:

• Semiconductor lasers;
• Dynamics and stability;
• Narrow linewidth lasers;
• Feedback-induced dynamics;
• VCSELs;
• Ring lasers;
• Semiconductor disk lasers;
• Neuromorphic computing based on semiconductor lasers;
• Quantum dot lasers;
• Frequency combs;
• Integrated lasers;
• Pulse lasers.

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.
