In the context of guided optics, the authors derive, analytically and geometrically, a rigorous general criterion to de- sign wavelength-insensitive interferometers with mirror symme- try, which are needed forwavelength multiplexing/demultiplexing. The criterion is applied to a practical case, resulting in an interfer- ometer that works on a band wider than 70 nm.
