Research on Nonlinear Optics with 2D Materials

Dear Colleagues,

The discovery of graphene in 2004 has sparked a significant surge in research and development activities focused on two-dimensional (2D) materials, including graphene, black phosphorus, transition metal dichalcogenides (TMDCs), hexagonal boron nitride (hBN), and graphene oxide (GO). These materials, with their atomically thin and layered structures, exhibit remarkable optical properties that differ from those of conventional bulk materials. They possess an ultrafast broadband optical response, large optical nonlinearities, and strong excitonic effects.

In recent years, there has been growing interest in exploring the nonlinear optical properties of 2D materials, both for laboratory research purposes and potential practical and industrial applications. Studies have shown that 2D materials like graphene, graphene oxide, and MoS₂ exhibit giant Kerr nonlinear responses, several orders of magnitude higher than those of bulk materials such as silicon. Additionally, 2D materials have demonstrated superior performance as broadband, fast-recovery, saturable absorbers for mode-locking in ultrafast pulsed fiber lasers.

Therefore, this Special Issue aims to showcase research papers and review articles that delve into the field of nonlinear optics with 2D materials. The focus includes investigating the nonlinear optical properties of 2D materials, such as saturable absorption, multiphoton absorption, and second- or third-order nonlinearity. Furthermore, the application of these properties in ultrafast all-optical signal generation and processing will be explored.

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. Crystals 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.
