The effect of back illumination with improved optical absorption has been analyzed for an ion-implanted GaAs OPFET considering the Pearson IV distribution of impurities. Plots have been made for two photo voltages developed across the substrate active layer junction and the Schottky junction. The drain-source current is significantly enhanced for the device when a fiber is inserted up to the active layer substrate junction compared with the case where the finite substrate effect is taken into account
