Random distributed-feedback Raman fiber lasers (RRFLs) are promising contenders in the applications of remote sensing, biotechnology, imaging, thanks to the unique properties on low coherence and w…
Establishing cognitive environments help cognitive robots understand human actions, languages and observed objects. In this paper, a cognitive robotic model based on a novel spiking bidirectional a…
Composite index is a powerful and popularly used tool in providing an overall measure of a subject by summarizing a group of measurements (component indices) of different aspects of the subject. It…
A novel fast-response sensitivity-enhanced high-temperature all-fiber Fabry–Pérot high-pressure sensor formed with a hard-core diaphragm is proposed and demonstrated. The structure can effective…
Optical mode exchange is an important technology for advanced mode-division multiplexing (MDM) interconnection networks, which provides enhanced flexibility by swapping signals between different mo…
Optical vortex beams (VBs) carrying orbital angular momentum (OAM) have shown significant multiplexing ability in radio-over-fiber communication by virtue of their intrinsic mode orthogonality. How…
High-resolution representations are essential for position-sensitive vision problems, such as human pose estimation, semantic segmentation, and object detection. Existing state-of-the-art framework…
Structured light beams (SLBs), mainly including vortex beams (VBs) and cylindrical vector beams (CVBs), have received significant attention in optical communications due to orthogonal orbital angul…
In this article, we present a W-band (3, 1) millimeter-wave vector signal generation based on frequency-quadrupled modulation and nonlinearities tolerant modulation by one Mach-Zehnder modulator (M…
The performance of free-space optical data transmission is severely deteriorated by the fluctuation of optical signal intensity, which is resulted from the bias drift of electro-optical modulation …
