✦ Synopsis

The optical properties of (GaAs) ({ }{n} /) (AIAs) ({m}) superlattices in the infra-red spectral region have been studied. The confinement of optical phonons has been observed in both GaAs and AlAs layers of superlattices under investigation. The superlattice modes caused by the coupling between Lo phonons and collective intersubband excitations have been found in doped superlattices. Macroscopic and microscopic calculations have been used for the analysis of experimental results. Good agreement with experiment has been obtained.

Cyclotron resonance (CR) measurements have been carried out to evaluate the effective mass of electron in (InGaAs) n /(GaAs) n superlattices (SLs) and (InGaAs) n /(AlAs) n SLs. To clarify the dependence of cyclotron mass on the monolayer number n, we measured CR signals using pulsed high-magnetic fi
