Special Issue Information
Dear Colleagues,
The unique structure of slot-waveguides has received mounting interest since it was first demonstrated. In this structure, the optical field is confined inside the low-refractive-index material (slot region), which is surrounded by a high-refractive-index material, usually silicon. In this structure, the electric field of quasi-TM mode displays substantial discontinuity between low-refractive-index and high-refractive-index materials. Therefore, light is strongly confined in a nanometer-wide region of the slot with a low level of refractiveness. Although the light is guided and enhanced in low-refractive-index material, the guiding mechanism still operates based on total internal reflection. Using this unique structure leads to a variety of advantages, such as a small beat length of the guiding light and a strong confinement in the slot region, yielding extremely low losses. Another benefit is that CMOS-compatible materials and technology can be used in slot-waveguide fabrication.
Thus, slot-waveguide technology has become a significant subject of research and growth in the understanding of nanometer-scale photonic devices. It allows low-cost optical devices by using common semiconductor fabrication techniques and their relatively simple integration with microelectronic chips.
We invite investigators to submit papers that discuss the development of optical devices based on slot-waveguide technology.
Potential topics include but are not limited to:
- Semiconductor-materials-based slot-waveguide technology;
- Tapers and couplers for coupling light to nano-silicon chip;
- Multiplexer/demultiplexer for o/c-band range;
- Power combiner/splitter;
- Grating coupler, ring-resonator, MZM;
- Special optical fibers;

- Amplifiers and lasers;
- Study new slot-waveguide structure;

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
