Special Issue Information
Dear Colleagues,
Silicon-based photonic integrated circuits (PICs) developed on standard silicon platforms can meet the information interaction needs of society in the “post-Moore’s Law era”. They are emerging as a competitive technology that can be used to resolve the “communication bottleneck” in current data centers and high-performance computing systems, where issues related to the power and speed of traditional electrical interconnects have become increasingly important. Using photons instead of electrons for data transmission offers advantages such as high-speed operation, low power consumption, and high-capacity transmission. Building PICs on industry-standard Si platforms lends them additional benefits like an ultra-low cost, mass manufacturing, high integration density, and scalability—essential features for future consumer applications like automobiles, metrology, and bio/chemical sensing. Furthermore, constructing PICs on Si facilitates their co-integration with Si microelectronics and enables the development of high-performance multi-functional Si-based optoelectronic integrated circuits.
Silicon exhibits several properties that make it a promising photonics material: it possesses a high refractive index compared to that of its oxide counterparts, low loss at communication wavelengths, and a substantial thermo-optic coefficient for tuning purposes. Leveraging these attributes has led to the demonstration of various photonic components on integrated Si photonics platforms, including mode couplers, tunable filters, and optical modulators. However, due to its nature as an indirect bandgap material, silicon's light emission efficiency remains limited; thus, laser sources based on silicon continue to pose significant challenges in terms of their integration into photonics.
This Special Issue aims to present research papers and review articles that focus on silicon-based photonic technology and devices, including the concepts and physics underlying silicon-based laser sources, waveguides, modulators, amplifiers, couplers, filters, and photodetectors and their fabrication processes.

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 2600 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.
