Phase noise arises from random fluctuations in the phase of oscillators and signal generators and represents a fundamental impairment in modern communication systems. It manifests as unwanted phase ...

Continuous Phase Modulation (CPM) constitutes a family of constant-envelope digital modulation techniques in which symbol transitions occur with continuous phase trajectories. By maintaining a ...

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...
