Cubic Nonlinear Optical Effects in Conjugated 1D II-Electron Systemsent a class of interesting highly nonlinear optical material with a principal drawback — the response time. Although the rise times are quite fast (of the order of a few ps) the decay time is an order of magnitude slower. The large nonlinearity of these materials is due to the large polarizability o

Stationary Solutions for the Excitonic Optical Stark Effect in Two and Three Dimensional Semiconduct theory. Due to many-body interactions one obtains an exciton optical Stark shift with an approximately constant (2d) or slightly increasing (3d) exciton oscillator strength in agreement with several recent experiments and in striking contrast to corresponding atomic observations. Apparently deviati

Exciton Stark Shift : Biexcitonic Origin and Exciton Splittingd. in two and three dimensions, disappears when the laser is turned off. This property made the exciton stark shift particularly attractive as it can be used for ultrafast optical gates. Very recently, another nice aspect of the exciton stark shift has been predicted. and verified experimentally.: u
