Abstract

We propose and theoretically investigate mid/far-infrared photodetectors based on frequency up-conversion in a near-resonant cascade of interband and intersubband transitions in high optical nonlinearity asymmetric quantum well structures. Such structures can yield high detectivity and responsivity in the bandwidth of the order of 30% of a central frequency in the mid-infrared range. Resonant up-conversion detectors can be designed for both collinear and perpendicular pump and signal beams. They can be integrated with semiconductor pump lasers to yield compact devices. We present specific device designs based on GaAs/AlGaAs and InGaAs/AlInAs heterostructures and calculate their expected figures of merit.
