Abstract :
I present a summary of my work on developing and characterizing semiconductor materials with greatly-reduced carrier lifetimes, and describe some preliminary demonstrations of ultrafast switching devices based on these materials. Recently, we have shown that low-temperature MBE-grown GaAs shows great promise for use in ultrafast all optical devices, and we have observed in this material the largest nonlinear optical effects ever seen with picosecond response. We have conducted a detailed study of the dynamics of the nonlinear optical properties of this material as a function of wavelength, optical power, and material parameters
