Monolithic GaAs detector-amplifier channels and arrays have been fabricated for use in the 0.81 - 0.85 pm wavelength range. The circuits were fabricated using a multilayered GaAs/AlGaAs/GaAs structure grown on semi-insulating GaAs. The AlGaAs layer provided electrical isolation between the upper MESFET layer and the lower n- photoconductor layer. Typical rise times of discrete photoconductors in response to 0.84 μm wavelength optical exci-tation were in the range of 1.5 - 4 ns. Rise and fall times of integrated detector-amplifier single channel circuits of 9 ns and 28 ns, respectively, were observed in response to 0.84 pm optical excitation.
