Optoelectronic hybrid logic gates that accept light as an input and produce output light are implemented. These gates are based on phototransistor/LED combination through optocoupler device. Only two optocouplers were used to demonstrate the functionality of basic gates, namely inverter, OR, AND, NOR, NAND, XOR and XNOR gates. The circuits were simulated and tested in the lab to further demonstrate their functions.
