Dual-comb source (DCS) generation occupies the central position to the versatilities of dual-comb applications. The single-cavity-based DCS generation is an emerging technology which provides super…
Optical frequency domain reflectometry (OFDR) is an attractive locating technology for distributed acoustic sensor (DAS) due to its high spatial resolution, but the detectable bandwidth of vibratio…
We report watt-level mid-IR Dy 3+ - and Er 3+ -doped all-fiber lasers using highly resistant dielectric-coated fiber mirrors. The fiber pigtail mirror is specifically designed for dichroic operatio…
We target the problem named unsupervised domain adaptive semantic segmentation. A key in this campaign consists in reducing the domain shift, so that a classifier based on labeled data from one dom…
This paper investigates the physical-layer security for water-to-air (W2A) visible light communication (VLC). The impacts of surface fluctuation and underwater scattering on the channel gain are th…
With the development of Internet of Things technology and artificial intelligence, the electric field sensor is required to be miniaturized, high performance, and low cost. At present, the commerci…
We propose and demonstrate a selectively microfluidic-infiltrated method for the group birefringence regula-tion in a microstructured optical fiber. Meanwhile, an Optical Frequency Domain Reflectom…
Optical microfiber-based refractometer, which relies on modal interference operating near the dispersion turning point (DTP), has attracted a high level of research interest. The ultrahigh sensitiv…
While deep neural networks (DNNs) deliver state-of-the-art accuracy on various applications from face recognition to language translation, it comes at the cost of high computational and space compl…
