Abstract

In the fused biconical taper process (FBT) the mode diameter of the optical fields within the fibers are spread to the extent that the surrounding medium acts as the fiber cladding. Usually this medium is air whose optical properties are benign resulting in stable devices. However, if the coupler is recladded with a material other than air, the optical fields spread further into the cladding region and the behavior of the coupler becomes substantially more sensitive to variations in the refractive index of the cladding material. In this paper we report the results of a study of recladded FBT couplers. Experimental results will be presented and compared to the predictions of a model previously used to describe the coupling characteristics of FBT couplers.
