本文对三种不同类型的3×3光纤共线耦合环形腔进行了系统的理论分析。首次对基于共线3×3光纤耦合器的双环谐振器进行了理论分析。得到了光纤环形腔的输出场和输出光强的表达式。通过使用计算机系统软件，可以很容易地获得这些输出强度。这三种类型的谐振器都使用一个共线的3×3光纤耦合器作为关键器件，其中三根光纤在同一平面上。研究发现，这些光纤环形腔各有其独特的特性。它们可用作光纤滤光片、高相位灵敏度传感器和密集双通道波分复用器(WDM/WDDM)。
We present a systemic theoretical analysis of three different types of optical fiber ring resonator using a collinear 3×3 fiber coupler. It is the first time that the theoretical analysis of dual ring resonator based on a collinear 3×3 fiber coupler is presented. Expressions for the output fields and output intensities of the fiber ring resonator are obtained. By using computer system software one can obtain these output intensities easily. The three types of resonators all use a collinear 3×3 fiber coupler as key device in which the three fibers are in the same plane. It is found that these fiber ring resonators have their own special characteristics. They can be used as fiber filter, a sensor with high_phase sensitivity and densely spaced two_channel wavelength division multi/demultiplexer(WDM/WDDM).
