The light propagation through a multimode fiber is used to increase information security during data transmission without the need for cryptographic approaches. The use of an inverse precoding method in a multimode fiber-optic communication network is based on mode-dependent losses on the physical lay...
Three-dimensional (3D) nano-printing of freeform optical waveguides, also referred to as photonic wire bonding, allows for efficient coupling between photonic chips and can greatly simplify optical system assembly. As a key advantage, the shape and the trajectory of photonic wire bonds can be adap...
In optical fiber communications, there is a long-term trend towards more and more expanding the transmission capacities, as data traffic keeps growing at a large rate. Obviously, there is thus an interest in maximizing the transmission capacity per fiber, and one of the technological options is ...
In addition, some effective channel allocation schemes have been proposed, which can effectively suppress the noises on the quantum channels [23–27]. However, with the improvement of data requirements, the existing SSF is gradually approaching its capacity limit, and it is very difficult to ...

Recently, the MuPPetS method (Multi-Population Pattern Searching Algorithm for Flow Assignment) was proposed and seems to be a promising tool for tackling high-dimensional, hard optimization problems. The MuPPetS is a linkage learning method that minimizes the negative effects of typical EA bottlenecks...
In theory, a single multi-core optical fiber with FBG sensors is sufficient for reconstructing three-dimensional shapes. However, they utilized four multi-core optical fibers, introducing redundant fibers to enhance the reliability of the sensing system in case of a failure in a single fiber Bragg...
Mode-division multiplexing (MDM) technology has drawn tremendous attention for its ability to expand the link capacity within a single-wavelength carrier, paving the way for large-scale on-chip data communications. In the MDM system, the signals are carr
in boosting the data transmission capabilities required for B5G applications. The NICT will complete in 2024 the first fully functional prototypes of a series of miniaturized laser-communication terminals for multiple platforms. These terminals are designed to adapt to a wide range of requirements to ...
In the data-mining framework, several state-of-the-art machine learning (ML) models along with one advanced deep learning (DL) model are used for training and testing. The proposed VSC-HVDC relaying system is comprehensively tested on a symmetric-monopolar-multi-terminal VSC-HVDC system and ...
