摘要：

The optical properties of an AlInAs/InP type-II superlattice are studied at room temperature. The photocurrent spectra have peaks that are attributable to excitons. An electroabsorption experiment confirms that the peaks are enhanced by applying an electric field. The change in absorption coefficient occurs at wavelengths of around 1 μm, where the linear absorption coefficient is small. Time-resolved photoluminescence shows the relaxation time is close to those in type-I superlattices.
