Abstract

We will review recent work on the development of low-temperature-grown semiconductor materials that has demonstrated the potential of these materials for ultrafast all-optical device applications. This work has led to an understanding of the dynamics of optically-induced absorption and refractive index changes, and the way m which the optical properties can be tailored by adjusting material growth and annealing conditions. We will then discuss some ultrafast switching and signal-processing devices based on these materials.
