Description
Summary:Realization of logical gates in the optical domain is a crucial part of current research to take the advantages of light speed in future demands, an example optical computer motherboard. Here, this paper proposed a simple reconfigurable XOR/OR gate using Two-Dimensional (2D) Photonic crystal structure. The performance of the device is analyzed using 2D finite difference time domain method. The dimension of the proposed crystal structure is 12.5 µm × 12 µm. The field distribution has been measured and displayed to indicate the performance of the logic gates. The proposed structure is very compact with a low latency of 120 fs.
