Split-cavity cross-coupled extrinsic fiber-optic interferometric sensor

Abstract

A new configuration of the fiber-optic extrinsic Fabry–Perot interferometer is demonstrated. This configuration utilizes two sensor heads on a single directional coupler in a split-cavity cross-coupled extrinsic fiber interferometric (SCEFI) arrangement to provide a four-beam interference. The need for quadrature phase biasing is eliminated, with a new spectrum analysis detection scheme devised for the SCEFI in a no-feedback condition. Good agreement between the model for interference and the experimental results is demonstrated. Wide applications for fiber sensor multiplexing and split-cavity étalons for filters in wavelength-division-multiplexing systems are indicated.
