Analysis of Optically Active Material Fibers
Abstract
This report describes a method of producing, and test results of, optical fibers having an optically active material at the core/cladding boundary. Two fibers were made and tested. The first has a thin AlCu alloy strip running the length of the fiber, the width of the strip covering approximately fifteen degrees of arc as seen looking at the fiber's cross section. The second has a thin CdTe semiconductor layer covering the fiber core. Both the AlCu strip fiber has absorption resonances in the transmission spectrum at 449 nm, 935 nm and 1140 nm, and exhibits both a polarization sensitive absorption at 1140 nm and birefringence at 1320 nm. The CdTe fiber exhibits a step in the transmission spectrum at a wavelength of 630 nm. This step is shifted towards shorter wavelengths from its value of 827 nm in the bulk material of the fiber preform.
