Optimizing spin polarization in quantum dot vertical-gain structures through pump wavelength selection
Najm Alhosiny, Sami S. Alharthi, J. Doogan +2
Spintronic applications require an efficient injection of spin-polarized carriers. We study the maximally achievable spin polarization in InAs quantum dots in a vertical-cavity gai…
Optical pattern formation in self-focusing and self-defocusing diffractively thick media
G. Labeyrie, I. Krešić, R. Kaiser +1
Cold atomic clouds constitute highly resonant nonlinear optical media, whose refractive index can be easily tuned via the light frequency. When subjected to a retro-reflected laser…
Continuous Acceleration Sensing Using Optomechanical Droplets
Gordon R. M. Robb, Josh G. M. Walker, Gian-Luca Oppo +1
We show that a Bose--Einstein Condensate illuminated by a far off-resonant optical pump field and its retroreflection from a feedback mirror can produce stable, localised structure…
Spontaneous atomic crystallization via diffractive dephasing in optical cavities
Adrián Costa-Boquete, Giuseppe Baio, Gordon R. M. Robb +3
The design of an experiment on the spontaneous crystallization of a laser-cooled, but thermal atomic cloud into a hexagonally structured phase is discussed. Atomic interaction is m…
Temperature Dependence of Spontaneous Switch-on and Switch-off of Laser Cavity Solitons in Vertical-Cavity Surface-Emitting Lasers with Frequency-Selective Feedback
J. Jimenez, G. -L. Oppo, T. Ackemann
A systematic experimental and numerical investigation of the conditions for the spontaneous formation of laser cavity solitons in broad-area vertical-cavity surface-emitting lasers…
Thick-medium model of transverse pattern formation in optically excited cold two-level atoms with a feedback mirror
W. J. Firth, I. Kresic, G. Labeyrie +2
We study a pattern forming instability in a laser driven optically thick cloud of cold two-level atoms with a planar feedback mirror. A theoretical model is developed, enabling a f…
