Special Issue Information
Dear Colleagues,
With the rapid development of bandwidth-intensive applications, optical networks have experienced a substantial increase in traffic. Theseoptical networks are highly vulnerable to security threats such as eavesdropping and attacks. Photonic firewalls, which can perform data identification and intrusion detection directly at the optical layer, are emerging as high-speed, low-energy network security tools. A core part of photonic firewalls is the all-optical matching system, which comprises all-optical logic gates such as the AND gate, NOT gate, XOR gate, etc. However, we continue to face the following challenges: First, SOA-based matching structures are unable to achieve all-optical matching at 40G and higher rates. In addition, there is a lack of matching structures for high-order modulation formats and existing structures that are suitable for amplitude signals. Furthermore, there is a lack of matching models for arbitrary modulation formats, where each modulation format corresponds to a set of matching structures. Lastly, the existing matching structures cannot handle the impact of system noise on matching, limiting the application of the current structures. These challenges highlight the need for further in-depth research to develop more effective solutions.

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.
