—In this paper, a more fundamental approach is used in defining optical crosstalk. This is achieved by analyzing the contributions of the non-interacting terms in the probability distribution of detection. Ideally, the detector registers the photons from the source field if and only if an interaction between the source field and the detector occurs. However, there are terms in the probability distribution that suggests that detection occur even when the detector atoms do not interact with the source photons. This is interpreted as the sources of optical crosstalk and it can be argued that these sources of optical crosstalk are due to (a) the secondary photon emission occurring in the bulk of the material which can either be coming directly from the incident photons or from the thermal excitations of the detector atoms; and (b) the interaction of the detector with the vacuum field.
