Broadband Terahertz Detection by Laser Plasma with Balanced Optical Bias
Sensors, 2022 Using a controlled optical bias and balanced geometry, we propose a new scheme for broadband terahertz detection by laser-gas interaction without high-voltage manipulation. Compared to the conventional optical bias scheme, the common noise is reduced and

Broadband noise decoherence in solid-state complex architectures [PDF]
, 2009 Broadband noise represents a severe limitation towards the implementation of a solid-state quantum information processor. Considering common spectral forms, we propose a classification of noise sources based on the effects produced instead of on their ...

All-Optical broadband phase noise emulation [PDF]
Advanced Photonics Congress, 2012 We demonstrate and characterize a technique to emulate broadband phase noise. This is achieved by exploiting cross-phase modulation induced spectral broadening, in a highly nonlinear fiber, of a signal from an intense incoherent light source.

Fluctuations and Pinning for Individually Manipulated Skyrmions
Frontiers in Physics, 2021 We numerically examine the dynamics of individually dragged skyrmions interacting simultaneously with an array of other skyrmions and quenched disorder. For drives just above depinning, we observe a broadband noise signal with a 1/f characteristic, while
