Abstract

The emission properties of a graded-index thermoplastic polymer optical fiber and a step-index thermosetting one, both doped with rhodamine 6G, have been studied. The work includes a detailed analysis of the amplified spontaneous emission together with a study of the optical gains and losses of the fibers. The photostability of the emission of both types of fibers has also been investigated. Comparisons between the results of both doped polymer optical fibers are presented and discussed.

Keywords: amplified spontaneous emission; light-emitting polymers; optical gain; polymer optical fibers; rhodamine 6G; thermoplastic fibers; thermosetting fibers.
