Lithium Niobate on Insulator: Technologies, Components and Applications

Dear Colleagues,

It is our pleasure to invite you to contribute to the Special Issue of MDPI Photonics that will be dedicated to the emerging field of lithium niobate on insulators. 

Due to its excellent piezoelectric, electro-optical, linear, and nonlinear optical properties, lithium niobate (LN) has a crucial role in a wide range of applications, such as optical parametric amplifications and electro-optic integrated devices for optical communications. In recent years, a huge amount of interest in this material has arisen thanks to the development of LNoI (lithium niobate on insulator) photonic platforms, that allow the exploitation of the abovementioned LN properties in integrated optical components and systems exhibiting ultralow loss and high optical mode confinement.

The currently available easy access to integrated photonic foundries has enormously accelerated the development of compact integrated optical components, and it offers several opportunities for the development of novel signal-processing devices and for power-efficient light generation and amplification while showing a compact footprint.

The aim of this Special Issue is to put together a collection of papers covering different aspects of the LNoI platform, ranging from technological and design aspects to integration, packaging, and application, so as to highlight the most recent findings and trends in this continuously and rapidly evolving field.

The topics of interest for the Special Issue include but are not limited to the following list:

• Thin film deposition techniques for LN on insulators;
• LN-integrated modulators;
• LNoI optical integrated waveguides and components;
• Integrated devices for nonlinear processing and frequency generation;
• LNoI integration with other platforms;
• LNoI for quantum photonics.

New research results submissions, letters, or full-length papers, dealing with experimental results and/or theoretical analyses, are welcome. Critical reviews of results already reported in the literature may be accepted after a preliminary discussion to avoid duplications.

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.
