Phase amplitude coupling of semiconductor lasers
SPIE Proceedings, 2006Quantum-dot semiconductor lasers have several distinctive features when compared with bulk and quantum-well devices. The phase-amplitude coupling of such devices was predicted to be near zero, but several experiments have shown this not to be generally the case. Here, we review several experimental investigations and their theoretical underpinnings.

Assessment of dynamic phase amplitude coupling using matching pursuit
Journal of Neuroscience Methods, 2022Neuronal transmission and communication are enabled by the interactions across multiple oscillatory frequencies. Phase amplitude coupling (PAC) quantifies these interactions during cognitive brain functions. PAC is defined as the modulation of the amplitude of the high frequency rhythm by the phase of the low frequency rhythm. Existing PAC measures are

A neural mass model of phase–amplitude coupling
Biological Cybernetics, 2016Brain activity shows phase-amplitude coupling between its slow and fast oscillatory components. We study phase-amplitude coupling as recorded at individual sites, using a modified version of the well-known Wendling neural mass model. To the population of fast inhibitory interneurons of this model, we added external modulatory input and dynamic self ...

Computing Phase Amplitude Coupling in EEGLAB: PACTools
2020 IEEE 20th International Conference on Bioinformatics and Bioengineering (BIBE), 2020Phase-Amplitude Coupling (PAC) in electrophysiological signals refers to the transient interplay of activities in different frequency ranges, wherein phase in a low-frequency band and amplitude in a high-frequency band are in some way dependent. PAC phenomena have received increasing interest in neuroscience given the growing evidence of their apparent

Granger Causality Based Directional Phase-Amplitude Coupling Measure
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021Phase-amplitude coupling (PAC), which quantifies the coupling between the amplitude of a fast oscillation and the phase of a slow oscillation, is reported as a possible mechanism that controls the flow of information in the brain. Although there is ample evidence suggesting that neural interactions are directional, conventional PAC measures mostly ...

Phase amplitude coupling in spectral phase modulation
IEEE Journal of Selected Topics in Quantum Electronics, 1998We report the experimental study of spatio-temporal coupling in spectral phase modulation. Spectral phase modulation relies on the creation of a Fourier plane where spectral components are dispersed and independently focused on a modulator, which allows to locally change the optical path.

Optimal Optical Beamsteering with Phase-Amplitude Coupled Elements
Conference on Lasers and Electro-Optics, 2022A new generation of spatial light modulators enables high speed operation. However, amplitude-phase coupling of elements makes optimal beamforming a computationally expensive task. In this work we present an analytical solution to this problem.

Phase-amplitude coupling of optically-injected nanostructured semiconductor lasers
2014 IEEE Photonics Conference, 2014In injection-locked lasers, the phase-amplitude coupling cannot be characterized by the FM-to-AM ratio. The former exhibits a resonance due to the injected field and the equivalent a-factor can be larger than that of solitary laser.

Matching Pursuit Based Dynamic Phase-Amplitude Coupling Measure
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020Long-distance neuronal communication in the brain is enabled by the interactions across various oscillatory frequencies. One interaction that is gaining importance during cognitive brain functions is phase amplitude coupling (PAC), where the phase of a slow oscillation modulates the amplitude of a fast oscillation.
