Paper Abstract

This paper describes the test apparatus and circuitry used to make measurements of pulsed light conductance on samples of high resistivity (107 Ω-cm) gallium arsenide switching devices, having nominal 25 PM and 700 Pm gap spacings. Differences in conductance are observed on variously grown samples. Maximum peak light conductance obtained was ≈2 millisiemens for an effective irradiated optical power on the (25 μm) gap of approximately 130 milliwatts (λ = 850 nm). Comparisons are made between the observed pulse measurements and the pulse waveforms generated by computer simulation using a model based on a theoretical analysis of the relationships between photoconductance and irradiated optical power.
