Schrodinger equation with a spatially and temporally random potential: Effects of cross-phase modulation in optical communication
A. G. Green, P. B. Littlewood, P. P. Mitra +1
We model the effects of cross-phase modulation in frequency (or wavelength) division multiplexed optical communications systems, using a Schrödinger equation with a spatially and t…
Gain in a quantum wire laser of high uniformity
Hidefumi Akiyama, Loren N. Pfeiffer, Masahiro Yoshita +5
A multi-quantum wire laser operating in the 1-D ground state has been achieved in a very high uniformity structure that shows free exciton emission with unprecedented narrow width…
Thickness-Dependence of the Coercive Field in Ferroelectrics
P. Chandra, M. Dawber, P. B. Littlewood +1
For forty years researchers on ferroelectric switching have used the Kay-Dunn theory to model the thickness-dependence of the coercive field; it works surprisingly well, despite th…
The crossover between lasing and polariton condensation in optical microcavities
M. H. Szymanska, P. B. Littlewood
We study a model of a photon mode dipole-coupled to a medium of two-level oscillators in a microcavity in the presence of dephasing processes introduced by coupling to external bat…
