Paper Abstract

The enhancement of the refractive index n((omega) ) close to interband transitions between confined quasi two-dimensional states of the valence and conduction bands of PbTe/Pb1-xEuxTe multiquantum well structures (MQWs) is studied experimentally as well as theoretically. The cusp-like changes of n((omega) ) are of importance for the proper design of quantum well lasers. We use transmission and reflectivity data of several MQWs with a well to barrier thickness ratio of about 4 - 10 which were deposited on 3 to 5 micrometers thick Pb1-xEuxTe buffers grown on BaF2 substrates for a comparison with calculated spectra.
