Summary form only given. We have carried out several experiments on device optimization for high absorption, on heterodyne detection up to 82 GHz, and on various nonlinear effects using GaAs/AlGaAs QWIPs. Near-ideal (/spl sim/100%) absorption quantum efficiency and room-temperature operation have been achieved, with specially designed devices having a large number of quantum wells and high well doping densities. Record-high frequencies up to 82GHz have been reached in heterodyne detection. Nonlinear effects caused by nonuniformity in potential distribution and laser intensity variation have been studied. Auto-correlation using a two-photon process has been demonstrated.
