Infrared Optoelectronic Materials and Devices

Dear Colleagues,

Thanks to the significant advances in physical and material fields, as well as the acceleration of nano-fabrication technologies, infrared optoelectronics demonstrate excellent performance in a plethora of applications, with wavelengths ranging from the near-infrared, mid-infrared, to far-infrared region, such as environmental monitoring, telecommunication, spectral fingerprints detection, medical engineering, and security.

Although breakthroughs have been achieved in developing novel infrared optoelectronic devices, a vast number of new scenarios continuously arise where high-performance infrared optoelectronic devices are expected. Conventional semiconductor materials are rarely found to meet the requirements of next-generation infrared emitters, modulators, and detectors that can operate with the narrow bandgap response, dynamic range, and room-temperature and high-speed modulation compatibility. Ever-growing interest lies in improving infrared lasers to ensure that they have outstanding properties, including high powers, ultrashort pulses, narrow-linewidth output, and wide operation bandwidth and tunability, and there is also a high degree of attention on ensuring low manufacturing costs and operation flexibility. Moreover, the miniaturization trend of infrared optoelectronic devices comes with complex architecture and a compact size but enhanced properties that have benefited from the advances in integrated photonic circuits and CMOS-compatible fabrication techniques. Plasmonic polaritons and nonlinear optical phenomena supported by nanophotonic devices and metamaterials can also enhance the performance and extend the research realm for infrared optoelectronics.

This Special Issue aims to demonstrate state-of-the-art academic research achievements on fundamental theories, models, and experimental results for the development of infrared optoelectronic materials and devices and their real-world applications. Researchers are invited to submit their articles to a broad range of topics, including, but not limited to, the following:

• Infrared optoelectronic materials’ growth and characterization;
• Novel devices based on low-dimensional structures and new materials;
• Nonlinear infrared technologies;
• Infrared lasers;
• Infrared emitters, modulators, and detectors;
• Infrared integrated photonics;
• Infrared metamaterials and metasurfaces;
• Infrared optical fibers;
• Infrared sensing;
• Infrared thermal imaging.

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.
