Abstract

Experiments were performed to show the feasibility of using two-photon absorption (TPA) in semiconductor waveguides as a nonlinear detector mechanism. Results show a strong pulse-width dependence of the photocurrent in GaAs waveguides and indicate that these nonlinear waveguide photodetectors can have subnanosecond electrical response times suitable for Gbit/s communications applications. With improvements in packaging, these devices can approximate the ultrafast optical thresholding function important for code division multiple access (CDMA) and other ultrafast network applications.
