Photonic Signal Processing: Fiber Optics and Waveguide On-Chip Technologies

Signal processing in optical networks is usually implemented based on digital signal processing. This involves several well-defined steps: optical-to-electrical conversion, electronic sampling, digital signal processing, and back electrical-to-optical conversion. In this sequence, the electronic sampling rate represents a clear bottleneck. A solution to circumvent this problem is to perform signal processing directly in the optical domain using a photonic signal processor; i.e., operating directly on the complex field envelope of a given light signal. Further, this operation can be performed analogically or digitally, and based on fiber-optics or waveguide on-chip technologies. Thus, a photonic signal processor can be used to perform a given—relatively simple—operation on a given light pulse.

Dear Colleagues:

It is a great pleasure and honor to present this Special Issue on “Photonic Signal Processing: Fiber Optics And Waveguide On-Chip Technologies” of MDPI’s open access journal Applied Sciences. It is a Special Issue which aims to present recent advances in photonic signal processing, and future prospects of this key, fundamental research area. All interested authors are encouraged to submit their newest results on photonic signal processors, either based on optical fibers or waveguide on-chip technologies, for possible publication in this issue of the Applied Sciences journal. All papers need to present original, previously unpublished work and will be subject to the regular standards and peer-review processes of this journal (including the usual pay fees, though there is a possibility of a special discount for a few selected contributions). Prospective authors are encouraged to also submit review proposals.

Potential topics include but are not limited to:

• Microwave filters;
• Pulse shaping;
• Wavelength conversion;
• Nonlinear optical processes;
• Integer and fractional calculus operators;
• Integer and fractional transforms;
• Theoretical design and modeling;
• All-optical tunable delays;
• Arbitrary waveform generators;
• Optical logic gates;
• Correlators;
• Analog and digital processing;

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
