Monolithic lithium niobate photonic chip for efficient terahertz-optic modulation and terahertz generation

Nature Communications
The terahertz (THz) range, bridging microwave and infrared frequencies, enables advanced imaging, sensing, communications, and spectroscopy. Analogous to microwave photonics, terahertz photonics offers a promising optical solution to critical THz ...

Coherent OAM generation from discrete chaotic phase surfaces

Scientific Reports
We demonstrate coherent orbital angular momentum (OAM) generation from chaotic phase screens with discrete integer-valued azimuthal bias. Through Fourier analysis, we prove that coherent OAM amplitude is nonzero only when the ensemble-averaged complex ...

Free-space Optical Communication based on Augmentation of OAM Modes

Guangtongxin yanjiu
【Objective】Atmospheric and oceanic turbulence causes the mode fading of optical Orbital Angular Momentum (OAM), thus being one of the main factors that deteriorate the performance of OAM-based Free-Space Optical Communications (FSOC) systems.
