Coupling and multiplexing between single mode optical fibers
Abstract
A design for a basic coupling configuration for all-fiber wavelength selective components is presented. Two bent single mode fibers each have their claddings etched away on a high curvature radius surface until the core trace appears. Setting the polished planes of the two fibers face-to-face produces a directional coupling. Choosing fibers with appropriate, different dispersion characteristics permits phase matching and hence improved wavelength selectivity. The results of computed wavelength dependencies on the dB power in one fiber when the second, coupled fiber is excited at a steady power level are given for fibers with different cladding indices.
