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

open access: yesAdvanced 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 ...

Low‐Loss Parowax‐Imprinted Diffractive Neural Network for Orbital Angular Momentum Terahertz Holographic Imaging

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of

Frequency‐Dependent Demethylation of Cancer DNAs by High‐Power Terahertz Radiation

open access: yesAdvanced Photonics Research, EarlyView.
Effective demethylation of cancer DNA is successfully demonstrated by resonant irradiation with high‐power terahertz (THz) waves at the 10 mW level, combined with metamaterial‐based THz filters. The dependence of spectral filtering on demethylation indicates that the resonant frequency of 1.6 THz of cancer DNAs plays a crucial role in reducing the ...
