Red micro light-emitting diodes (micro-LEDs) on silicon substrates are crucial for the realization of large-scale, high-quality, low-cost micro-LED displays, and are also beneficial for high-speed …
An advanced light source at blue-green waveband is the key to improve the link-distance and communication performance of an underwater wireless optical communication (UWOC) system. This work presen…
In this paper, we first utilize the interleaved single-carrier frequency division multiplexing (I-SC-FDM) scheme with a novel sparse weight-initiated deep neural network (SWI-DNN) equalizer for und…
In the present paper, we demonstrate the first outdoor free-space optical communication (FSOC) system with real-time video transmission in a 2-μm-band with a state-of-the-art data rate performance…
Due to the inherent vulnerability of deep neural networks (DNNs), the adversarial example (AE) attack has become a serious threat to intelligent systems, e.g., the failure cause of an image classif…
Poincare beams (PB), carrying spin angular momentum (SAM) and orbital angular momentum (OAM), play a significant role in a wide range of optical applications. The inhomogeneous polarization distrib…
In this work, we propose and demonstrate a high-stability polarization-based interrogation method using cross-correlation for optical fiber interferometric acoustic sensing. Specifically, an extrin…
Feature selection is to reduce both the dimensionality of data and the classification error rate (i.e., increase the classification accuracy) of a learning algorithm. The two objectives are often c…
Infrared absorption spectroscopy (IAS) is currently a powerful tool for gas sensing. Gas sensors based on IAS show advantages of high sensitivity, good selectivity and in-situ measurement. Typical …
