Abstract

Multi-wavelength infrared detection realized with two distinct superlattices separated by a blocking barrier was discussed. The blocking barrier separating the two superlattices allowed the photoelectrons from one of the superlattices to be collected under either voltage polarities. The photo-response was switchable between 7.5 ∼ 12μm and 6 ∼ 8.5μm by the bias polarity, and the spectral responsivity in each wavelength region was also tunable by the bias magnitude.
