Design and Analysis of High-Q, Amorphous Microring Resonator Sensors for Gaseous and Biological Species Detection

Abstract Details

2009, Master of Science (MS), Ohio University, Electrical Engineering (Engineering and Technology).
The need for biological species and gaseous detection has been increasing over the years with increased amount of pollution and evolving bio-weaponry. Hence an integrated sensor with high sensitivity and selectivity has been identified as very important. In this thesis we propose a design for a vertically coupled optical microring resonator for detecting gaseous and biological agents. An analytical analysis of the design is initially executed using the Marcatili waveguide method and later the design is optimized using Finite Element Methods (FEM). The design involves the optimization of the height, width, ring radius and coupling distance. Different types of losses are identified using analytical methods and their relation with the sensor performance is discussed. The design is finally tuned to achieve high Q. The sensitivity of the design is determined using numerical methods (FEM) and its relationship with Q is discussed. These results are analyzed with respect to fabrication tolerances. This thesis provides a solid background work for designing any microring resonator.
