Special Issue Information
Dear Colleagues,
Ever-emerging services and applications, such as cloud computation, big data, and the Internet of things, have imposed an exponentially growing capacity demand on communication systems and networks on all layers. In particular, conventional single-mode fiber (SMF)-based optical communication technologies, such as wavelength-division multiplexing (WDM), time-division (TDM), and polarization-division (PDM), have confronted fundamental scalability limits. The last decade has seen various technologies emerge as possible solutions for next-generation optical communications for sustainable capacity growth, by exploiting the only known uncultivated degree of freedom of light—the space domain. Space- and mode-division multiplexing (SDM and MDM)-based optical-fiber, free-space, and underwater communications have been extensively investigated at both system and component levels. Multi-core, multi-mode, few-mode fibers (MCF, MMF, and FMF) and the variations as their combinations are explored as the main platforms for SDM and MDM fiber transmissions, while major challenges including optical amplification and inter-channel coupling remain to be fully addressed. In pursuit of other key components of high efficiency and scalability, especially spatial/modal (de)multiplexers, significant developments have been witnessed recently by introducing sophisticated structured light manipulation techniques, for example, photonic lantern, multi-plane light conversion (MPLC), log-polar and spiral transform based mode sorters, and inverse-design based optical mode converters. This Special Issue seeks to showcase research papers, communications, and review articles that focus on new developments in the design, modelling, fabrication, and application of SDM/MDM devices and components.

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. 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.
