Mode division multiplexing (MDM) is considered to be an efficient solution to alleviate the exponentially increasing “capacity crunch”. Here, we numerically and experimentally demonstrate a hig…
The goal of image steganography is to hide a full-sized image, termed secret, into another, termed cover. Prior image steganography algorithms can conceal only one secret within one cover. In this …
Optical fiber shape sensing technology provides an excellent solution for the tracking and guiding of minimally invasive surgical instruments. However, when some large-deformed instrument operation…
A photonic-assisted reconfigurable LO harmonic downconverter with simultaneous image-rejection and RF self-interference cancellation (SIC) for in-band full-duplex communication is proposed and expe…
Problem definition: Complementary sourcing, with which a product depends on both a supplier’s and a manufacturer’s engineering and production efforts, is ubiquitous in modern supply chains. A u…
Coverage performance is very important for operators when commercializing NR networks due to its direct impact on service quality as well as CAPEX and OPEX. Compared to LTE, NR systems may operate …
The fabrication of GaN light-emitting diodes (LEDs) with on-chip photodetectors (PDs) based on flip-chip configuration is reported. The exposed sapphire plays a key role not only in light extractio…
Owing to its practical significance, multi-domain Neural Machine Translation (NMT) has attracted much attention recently. Recent studies mainly focus on constructing a unified NMT model with mixed-…
Long range phase-sensitive optical time domain reflectometer (φ-OTDR) sensing mainly employs distributed amplification in the sensing fiber. It requires the light to be injected into both ends of …
