Paper Abstract

Electric fields alter the optical properties of the various layers in a quantum well laser by the Franz-Keldysh effect or by the quantum confined Stark effect. The resulting features of an electroabsorption spectrum obtained by combination of dc and ac fields are characteristic for confined and unconfined states and allow the determination of transition energies, band gaps of bulk layers, internal fields and homogeneity of the sample. The results of two structures of different barrier height are compared with luminescence and photocurrent data and with model calculations.
