Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2

Advanced Optical Materials, EarlyView.
The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...

High‐Fidelity Information Transmission Through the Turbulent Atmosphere Utilizing Partially Coherent Cylindrical Vector Beams

Advanced Photonics Research, EarlyView.
A novel free‐space optical communication protocol that combines the benefits of partially coherent light sources with the decoding capabilities of convolutional neural networks is proposed. This approach establishes a robust communication link that can withstand atmospheric turbulence.

Biphoton Waveforms of Photon Pair from Velocity‐Selective Atoms in a Doppler‐Broadened Atomic Ensemble

Advanced Photonics Research, EarlyView.
Telecom‐band quantum light sources have significant practical applications in this domain. This study reports the high‐performance telecom‐wavelength biphoton generation from a hot vapor cell of 87Rb. For the first time, the beat phenomenon in the autocorrelation function of the signal photon with telecom wavelength due to the velocity‐selective ...

Tailoring Second Harmonic Generation via Strong Coupling in a One‐Dimensional Photonic Crystal Heterostructure

Advanced Photonics Research, EarlyView.
The strong coupling is investigated as an effective method to modulate the second‐harmonic generation (SHG) in the defect mode and Tamm plasmon resonances. Throughout the entire anticrossing Rabi splitting process induced by strong coupling, the difference in SHG efficiency between two resonances can be modulated by up to two orders of magnitude ...
