摘要: Voltage-controlled multicolor detection with a two-stack GaAs/AlGaAs superlattice structure is reported. Each stack contains a superlattice and current blocking layers. The responsivity of each stack has a voltage-tunable spectral range and can be turned on or off by controlling the bias polarity. In a back-to-back configuration of the two stacks, a variable detection range with peak wavelength at 5.5, 6.8, 8.5, and 10.8 mu m is achieved by changing the applied voltage at 45 K.
