The combination of an analytical approach with a geometrical representation, allows us to derive a rigorous general criterion to design wavelength insensitive interferometers with mirror symmetry, which are needed for wavelength multiplexing/demultiplexing using Bragg grating Mach-Zehnder add/drop filters. Numerical simulations corroborate the analytical results.
