Optical NOR Logic Gate Based on Dual Circular Photonic Crystal Ring Resonator
نویسنده
چکیده
We introduce a new configuration of optical NOR logic gateimplementedby using two symmetric circular shaped photonic crystal ring resonator made of dielectric Indium Phosphide rods in air substrate. The switching behavior of proposed optical gate was analyzed based on beam interference principle and perturbation theory. Numerical calculations were carried out by optiFDTD tool using a 2D FDTD domain technique through which high quality factor ‘Q’ microcavity produce as large as .90 transmitted power. Further, contrast ratio is calculated indicating high performance of proposed logic gate as 16.53db which is much higher than earlier reported values. The band gap is calculated using plane wave expansion method.

Add-Drop and Channel-Drop Optical Filters Based on Photonic Crystal Ring Resonators
Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). The broadest photonic band gap occurs at the filling ratio of r/a = 0.17. Two linear defect W1 waveguides couple to the ring....
