Abstract
A new type of optically controlled GaAs FET operating at 1.55 μm has been demonstrated. The current of the FET is modulated by the electric field induced by the photogenerated carriers in the p-i-n GalnAs/InP absorption region.1,2 This device makes possible a speed of operation that is higher than that obtainable with a direct-optical-control FET3 using photo-generated carriers in the channel as a modulation current.
