“…It is well known that the center-of-mass motion of excitons raises more than one propagating modes of exciton-polaritons in their band gap frequency, and the RHPS process has been used to observe the dispersion of polaritons 11,37,[47][48][49] and also to measure the translational masses of excitons and biexcitons.…”

“…8 shows the energetical shift of the HEP line a t hw, > E,/2 in dependence of np and the scattering angle. Some experimental results of [12] are also shown. The behaviour of the LEP line is similar to that of the HEP line but the energetical shift has opposite sign.…”

“…I n addition a double structure of the scattering line should be observable especially for hw, < E,/2. These structures result from taking into account the outconiing polaritons to be also renormalized in contrast to [12]. Fig.…”

“…L'indice de réfraction et les angles d'incidences a et ß déterminent l'angle de diffusion 0 à l'intérieur de l'échantillon. On peut, par contre, utiliser deux lasers à colorant différents et exciter l'échantillon des deux côtés [13]. Ainsi, le module du vecteur avec lequel l'état intermédiaire est excité est plus petit et un processus de recombinaison qui fait intervenir la b.s.p.…”

“…Les anomalies apparaissent quand, soit le polariton observé sur la b.i.p. ou son complément se trouve dans la région de forte variation de E| avec Qj [25][26][27][28][29]. Le fait que l'on observe les variations de la position de Rj et Rj avec l'intensité aussi quand le complément du polariton qui est observé se trouve dans la région perturbée, montre bien qu'il s'agit d'un effet dispersif et pas d'une simple réabsorption.…”
