Abstract

The authors report, for the first time, the new two-color quantum well infrared photodetectors (QWIPs) from a non-III-V semiconductor material system. The samples were grown on InP substrate by molecular beam epitaxy. X-ray diffraction and photoluminescence measurements showed high structural and optical quality of the samples. Two intersubband (ISB) absorption peaks in two different wavelength regions are observed in Fourier transform infrared measurements. The two-color photodetectors can be turned on separately or simultaneously in the two spectral regions. (
