Description
Summary:In this paper we are going to propose and design and optical structure capable of working as an optical OR and NOR gate. Nonlinear Kerr effect combined with a photonic crystal ring resonator to perform the required switching tasks of the logic gates. For the resulted structure the minimum intensity contrast ratio for OR and NOR gate obtained to be 25dB and 19.8dB respectively. The maximum delay of the structure is about 4ps.
