Self-Organization in Cold Atoms Mediated by Diffractive Coupling
Thorsten Ackemann, Guillaume Labeyrie, Giuseppe Baio +8
This article discusses self-organization in cold atoms via light-mediated interactions induced by feedback from a single retro-reflecting mirror. Diffractive dephasing between the…
Magnetic Phase Diagram of Light-mediated Spin Structuring in Cold Atoms
Guillaume Labeyrie, Ivor Kresic, Gordon R. M. Robb +3
When applying a red-detuned retro-reflected laser beam to a large cloud of cold atoms, we observe the spontaneous formation of 2D structures in the transverse plane corresponding t…
Analysis of spatial emission structures in vertical-cavity surface-emitting lasers with feedback of a volume Bragg grating
Yoann Noblet, Thorsten Ackemann
We investigate the spatial and spectral properties of broad-area vertical-cavity surface-emitting lasers (VCSEL) with frequency-selective feedback by a volume Bragg grating (VBG).…
Complexity of Polarized Spatial Patterns in Large Area Square VCSEL
I. V. Babushkin, N. A. Loiko, T. Ackemann
We consider pattern selection process in a wide aperture VCSEL near threshold. We show that for a square geometry of the laser aperture, the patterns formed at lasing threshold can…
