Optical High-Speed Information Technology (2019)

Dear Colleagues,

The field of optical high-speed information technology includes a wide range of topics, starting from basic to advanced research and technological applications, which have been given significant interest by different sectors. The successful demonstration of semiconductor lasers for optical communication stimulated a series of development in optoelectronics, including vertical-cavity surface-emitting lasers, light emitting diodes, semiconductor optical amplifiers, etc. Semiconductor structures, such as quantum wells, quantum wires, quantum dots, etc., with emissions corresponding to the desired wavelength for use in fiber optical telecommunication systems, have been investigated using various techniques including photoluminescence, time-resolved photoluminescence, photoluminescence excitation spectroscopy, and other ultra-fast optical spectroscopy, such as optical pump-optical probe spectroscopy, optical pump-terahertz probe spectroscopy, time-resolved excitation-correlation spectroscopy, etc. Furthermore, security in high speed and massive information transmissions are a major issue for this rapidly-evolving information-oriented culture. The rapid upgrading of digital computer technology can result in a fast decoding of standard code for scrambling data in secure communication systems, which can lead to eavesdropping. Research on quantum computing and communication methodology have also been evolving and have attracted significant attention from the global scientific and technological community. Alternatively, semiconductor laser based optical chaotic communication systems have been proposed to be efficient potential candidates for secure information processing technology due to the high speed and broadband capabilities with optical encoding and decoding.

The current Special Issue is formulated for articles presenting both reviews of most recent research outcomes and original research papers in the field of optical high-speed information technology. The research topics are not strictly restricted to the aforementioned research fields and can also cover wide range of related research fields, such as fiber optics, quantum computing, chaos, chaotic systems, synchronization of chaos, encoding and decoding, cryptography, optical communication, optoelectronic device fabrication and characterization, fiber materials, semiconductors, high electron mobility transistors (HEMT), and new relevant technological advancements.
