We present the 3D box-bender interferometer, which folds a Mach-Zehnder into a symmetric box using a polarization-rotating periscope with a 90° geometric phase shift to rotate the polarization in one arm for interfering two broadband orthogonally-polarized beams with equal optical pathlength and dispersion. We demonstrate its utility by interfering the orthogonally-polarized diffracted and undiffracted beams from an acousto-optic tunable filter.
