en Studying the Effects of Structural Parameters on the Optical Gain of Micro-Ring Resonators تخصصی Special پژوهشي Research The proposed system consists of micro-ring resonators (MRRs) with different radii. In this paper, the effects of structural parameters such as gap between the waveguides and the MRRs, width and height of the waveguides and the MRRs and MRR radii on the optical gain are studied. It is shown that by increasing the MRR radius the optical gain decreases and by increasing the width and height of the MRR and the waveguide and the gap, first the optical gain increases and then decreases. The properties of this system are numerically investigated by the finite-difference time-domain (FDTD) method. The proposed system consists of micro-ring resonators (MRRs) with different radii.
