Abstract

Studies of the angular dependence of cw degenerate four-wave mixing in n-type InSb have yielded a value for the diffusion length, l_D, of 60 ± 2 μm. From this, the dependence of l_D on photoexcited carrier concentration is calculated. A simple model has been developed to estimate the corresponding parallel-processing capabilities of semiconductor-based, all-optical, parallel-processing digital computing systems.
