Abstract

Forbidden (Formula presented) and (Formula presented) exciton transitions (where (Formula presented) and (Formula presented) are heavy-hole and light-hole, respectively) appear in magnetooptical spectra of quantum wells that undergo a type-I-type-II band-alignment transition, here for ordinary (In, Ga)As/GaAs multiple quantum wells and a single CdTe quantum well with a (Cd, Mn)Te semimagnetic barrier exhibiting a giant Zeeman effect. The oscillator strength becomes so strong in a field of 11.25 T that vacuum-field Rabi splitting is clearly seen in reflection spectra when the (Formula presented) exciton transition couples to the two-dimensional optical mode in a microcavity.
