We present an analytical model forthe photon recycling effect associated with the reabsorption of generated photons in a light-emitting diode (LED) driven by nonuniform current injected from a quantum well infrared photodetector (QWIP). The model is applied to the evaluation of the modulation transfer function and the external quantum efficiency in pixelless imaging devices based on the integration of a QWIP with a LED. The modulation transfer function and the signal external quantum efficiency of a QWIP-LED pixelless imager are calculated as functions of the structurl physical and geometrical parameters. It is shown that photon recycling is a significant factor that limits the spatial resolution of images and increases the external quantum efficiency.
