In this paper we present a novel optoelectronic device, called a photonic transistor, and we investigate its properties as they pertain to digital electronic applications. The photonic transistor design is based on a heterojunction configuration similar to a semiconductor optical amplifier, and can be used to construct either N-nary digital logic gates or binary Boolean logic gates. The properties of the photonic transistor are investigated using computer simulations, and the numerical results indicate that such a device can be successfully used in digital optoelectronic applications.
