摘要：

Predictions and measurements of a multimode waveguide interferometer operating in a fiber-coupled, "dual-mode" regime are reported. With a 1.32 mu m source, a complete switching cycle of the output beam is produced by a 10.0 nm incremental change in the 8.0 mu m width of the hollow planar mirror waveguide. This equates to a fringe spacing of similar to lambda/130. This is an order of magnitude smaller than previously reported results for this form of interferometer.
