Coherent optical control of correlation waves of spins in semiconductors

We have calculated the dynamical fluctuation spectrum of electronic spinsin a semiconductor under a steady-state illumination of light containing po-larization squeezing correlations. In this externally driven system we foundthat the contribution which is fourth order in the optical field is sensitive tothe squeezing phase of the light.

We have demonstrated the possibility tocontrol the spin fluctuations by optically modulating this phase as a func-tion of frequency in a pulse shaper. We found that the spin-spin correlationfunctions in time domain can be non-trivial in the case when the oppositepolarizations are used in combination with linear and quadratic phase func-tions.
