Femtosecond Laser Micromachining for Photonics Applications, Volume II

Dear Colleagues,

Femtosecond lasers are a formidable micromachining tool, applicable to a variety of materials. In particular, femtosecond laser processing has unique capabilities to alter the optical properties of most transparent dielectric substrates in a permanent fashion and with a micrometric resolution, thus, allowing the manufacture of innovative integrated devices for photonics applications.

One important application of this technique is the direct and rapid inscription of integrated waveguide circuits with three-dimensional layouts. In the last decade, such circuits have found impressive applications in diverse fields, which include optical sensing, telecommunications, astrophotonics, and quantum photonics. Femtosecond laser pulses have also been exploited to locally engineer the birefringence of substrates and to produce microstructured birefringent plates. Femtosecond laser nanostructuring at the diffraction limit further allows the inscription of gratings and photonic crystals, as well as dense optical storage of information.

The research community in this field is growing at a steady pace: Optical devices produced by this technology are increasing in complexity and novel ideas are continually being presented. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles on technological advances and novel applicative concepts of femtosecond laser micromachining, with a focus on optics and photonics.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines 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 2100 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.
