Abstract :
Three-dimensional finite-difference time-domain modelling of a travelling-wave heterojunction phototransistor is presented. The electromagnetic model allows the simultaneous simulation of the optical and microwave properties of the travelling-wave structure. The results clearly demonstrate the effect of velocity mismatch between the optical wave and the photogenerated electrical wave.
