In this work we report a investigation of the plasmon-longitudinal-optical (LO) phonon interaction effects on the intersubband and intrasubband collective excitation energies in a GaAs-Al n Ga 1Àn As rectangular quantum well wire. We observe a resonant split of the collective excitation energy into
