Abstract :
[en] The optoelectronic dc and RF behavior of an InAlAs–InGaAs optically controlled field-effect transistor based on a high electron mobility transistor layer structure is investigated at 1.3- um wavelength light. The device is backside-illuminated to increase the responsivity. A transistor with 0.3-u m gate length and an active area of 50 x 50 u m2 exhibits a responsivity of 235 A/W, at 11- W incident optical power. The photoconductive response is higher than for an metal–semiconductor–metal photodetector with the same InGaAs absorption layer thickness up to 10 GHz.
