Novel Fabrication Methods and Materials of Photonic Devices

Dear Colleagues,

In recent years, photonics has become a key enabling technology for the future. Photonic devices are everywhere in our societies and represent a fundamental aspect in several sectors of industry and services. Photonics is not limited only to lighting, communications, and photovoltaics, as observed in the last decades, but there is an exponentially rising demand for photonics in many other areas, considered inaccessible until now, such as healthcare, agriculture, archaeology, aerospace, and beyond for all-optical computing and quantum computing.

The growth of the photonics market is mainly due to the remarkable and fast improvements observed in the fabrication of photonic devices at micro- and nanoscale with new manufacturing techniques and novel materials. The strong compactness and integrability of photonic devices enable high-volume production with a decrease in system costs. Moreover, high-resolution and accuracy obtained with new manufacturing approaches can maximize light–matter interaction with an improvement of the performance at different length scales in several fields with the possibility to overcome the diffraction limit of light.

This Special Issue will focus on the latest advances of photonic devices and systems based on the development of novel fabrication methods, so enabling the use of photonics as a disruptive technology for the next generation of devices for communications, lighting, sensing, etc. Both review articles and novel research papers are solicited, covering the following areas:

• Original fabrication methods, techniques, and approaches in photonics.
• New materials and improvements in established photonic platforms (i.e., silicon platforms, plasmonics, metamaterials, 2D materials, hybrid systems).
• Fabrication of novel photonic structures for light control and manipulation down to nanoscale (i.e., resonant metasurfaces, nanosensors, metalenses, trapping nanotweezers)
• Methods for device integration on a single-chip to realize new photonic systems and platforms.

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 250 words) can be sent to the Editorial Office for assessment.

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.
