The performance of a family of dual GRIN lens multiplexers has been investigated with a ray tracing analysis. The dependence of the device’s insertion loss on several lens and input/output fiber parameters was examined. Several versions of this multiplexer were built and characterized. Certain versions were found to provide low loss and a relative insertion loss independence of wavelength.
