Abstract

Transport phenomena in signal-processing in the element (SPRITE) detectors are the critical link between the optical input and the electronic output of these devices. The properties of this link determine such important properties as the responsivity, the modulation transfer function (MTF), tire detectivity (D^*), and the noise power spectral density (PSD). The previous literature^1-3 has presented approximate solutions to the transport problem that neglect boundary effects, which have long been thought to play a major role in SPRITE behavior.^4,5 Here we present a new solution to the problem through the use of modal analysis. This method intrinsically includes the three-dimensional boundary conditions and thus is more complete than the previous analysis.
