Ultrafast Laser Written Photonic, Sensing and Microfluidic Circuits in Transparent Materials

Dear Colleagues,

Since the discovery that, thanks to nonlinear absorption,  tightly focused ultrashort laser pulses can induce highly localized permanent refractive index modification or even voids in a large number of transparent dielectrics, the technique of ultrafast laser inscription has received great attention for a wide range of applications. It has evolved from a curiosity to a viable platform for the rapid three-dimensional prototyping of small-scale circuits, in different contexts such as optical waveguiding, microfluidics, lab-on-chips, or quantum information science.

This Special Issue aims to explore the current state-of-the-art in applying ultrashort laser pulses for the micro or nano processing of different transparent materials, to review the basic techniques and technological challenges of 3D integrated photonics fabricated using ultrafast laser inscription and relevant to different research areas such as quantum information, sensing, or microfluidics. In general, this Special Issue aims to highlight the most recent progress in the field of ultrafast laser written optical components in transparent materials for different applications. Contributions that explore advanced laser writing techniques as well as those that discuss innovative photonic, sensing, or microfluidic devices and integrated platforms will be welcomed.

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. 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.
