Paper Abstract

We report the fabrication and characterization of the n-type InGaAlAs/InAlAs multiple quantum well structures, lattice- matched to InP, for the long wavelength IR detection. It is found that strong absorption resulted from the intersubband transition in the quaternary material is observable and the wavelength of the absorption varies with the well width while the barrier width is kept unchanged. Our experimental result are in good agreement with the theoretical estimation based on simple finite barrier model and can be confirmed by the photoluminescence data.
