Paper Abstract

A novel fiber-optic interferometer, the coupled fiber ring interferometer array (CFRIA) is proposed. The addition of one or more single-mode fiber directional couplers to the fiber ring interferometer results in a CFRIA. The theory based on the matrix method has been proposed for the calculation of the electric field intensity output of the CFRIA. Equations for calculating the transmittance are also derived. The transmission characteristics of two-, three-, and four- coupled CFRIA are calculated. It is shown that a suitable choice of coupling ratio results in ripple-free transmission curves. Various loss effects are given. The CFRIA proposed here will have potential applications in the fiber sensor array, spectroscopy, and coupled resonator fiber lasers.
