Photonic Generation of a Tunable Dual-Chirp Microwave Waveform

A photonic-assisted tunable dual-chirp microwave waveform generator based on optical heterodyne detection is proposed and experimentally demonstrated. In the proposed scheme, a three-electrode dist…

A THz Integrated Circuit Based on a Pixel Array to Mode Multiplex Two 10-Gbit…

We experimentally demonstrate a THz integrated circuit with a pixel-array-based orbital-angular-momentum (OAM) mode converter for the generation and multiplexing of multiple data-carrying OAM beams…

Modulation Bandwidth Enhancement and Frequency Chirp Suppression in Two-Secti…

We demonstrate a two-section distributed feedback (DFB) laser for direct modulation based on the reconstruction equivalent chirp (REC) technology. The two-section DFB laser exhibits a stable single…

Experimental Phase Stabilization of a 397-Channel Laser Beam Array Via Image …

A phase-locking module is firstly validated for coherent beam combining (CBC) systems of near 400 laser beams in dynamic noise environment. It is based on a 2-dimensional image processing in the ph…

On the Benefit of Privatization in a Mixed Duopoly Service System

We consider a mixed duopoly service system with two service providers (SPs): one private and the other public. The public SP’s objective is welfare maximization, whereas the private SP is profit …

Toward Holographic Video Communications : A Promising AI-Driven Solution

Real-time holographic video communications enable immersive experiences for next-generation video services in the future metaverse era. However, high-fidelity holographic videos require high bandwi…

Comparing the Performance of Evolutionary Algorithms for Sparse Multi-Objecti…

Many real-world multi-objective optimization problems (MOPs) are characterized by a large number of decision variables, where the decision variables are mostly set to zero in the Pareto optimal sol…

Global Stability and Canard Explosions of the Predator-Prey Model with the Si…

For the predator-prey model with the sigmoid functional response whose denominator has no real roots, the dynamics has already been characterized. Whereas, when the denominator has a real root, the…

Toward Multi-Functional 6G Wireless Networks : Integrating Sensing, Communica…

Integrated sensing and communication (ISAC) has recently emerged as a candidate 6G technology, aiming to unify the two key operations of the future network in a spectrum/energy/cost-efficient way. …
