Backscattering Coupling Effect in Square Ring Resonator
Backscattering coupling effect in square ring resonator is studied. Vector method has been proposed to analyze the optical path variation induced by reflectors′ displacement in square ring resonator. A mathematic model of backscattering coupling analysis has been established. This model can be applied to analyze backscattering coupling effect in any form of ring resonators. Backscattering coupling coefficient r as a function of mirror′s axial displacements has been obtained. The absolute value of r has a period of two wave lengths in optical path length. It shows that the initial machining error of the resonator has a great effect on backscattering coupling effect. It is important for the research on the backscattering coupling effect in ring resonator.
