title: Folded-beam design for a Martin-Puplett interferometer with substrate polarizers.
abstract: A polarizing interferometer requires a rotation of 45° between the input polarizer and beam-splitter polarizer. If substrate polarizers are used, however, the p polarization should be transmitted at both polarizers for highest efficiency. An out-of-plane configuration is presented that satisfies both criteria.
