Silica optical fiber derived from yttrium-aluminum-garnet (YAG) crystals is an excellent high-gain fiber due to their high rare earth ions doping concentration. It offers a new opportunity of addre…
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 …
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…
In this article, a novel Bayes-Adam-based multiple-input multiple-output (MIMO) equalizer was proposed and experimentally demonstrated for an orbital angular momentum (OAM) mode-division multiplexe…
Owing to the mutual orthogonality among different orbital angular momentums (OAM), OAM mode has been considered as a promising candidate for improving channel capacity and spectrum efficiency. Howe…
We develop a decomposition method based on the augmented Lagrangian framework to solve a broad family of semidefinite programming problems, possibly with nonlinear objective functions, nonsmooth re…
In recent years, heterogeneous integration (HI) has become a game-changing technology for the construction of complex photonic integrated circuits. Comparing to monolithic integration (MI) techniqu…
Optical surface wave excited by nanocoatings has enabled fiber-optic sensors with high sensitivity to the change in external environment generally characterized by bulk refractive index (RI). Nonet…
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 …
The stochastic block model is one of the most studied network models for community detection, and fitting its likelihood function on large-scale networks is known to be challenging. One prominent w…
