91212 Tunable Mach-Zehnder interferometer



The 3DOptix’s tunable Mach-Zehnder interferometer is assembled from three modules: beam splitter module, delay line module and a beam-splitter/combiner module. The incoming signal is split in a 99221 or 99021 3DOptix beam splitter, then the two beams are delayed in 99122 delay line module, which separates the beams into two parallel beams with 3’’/75mm interval. These beams are inserted into a 99222 3DOptix beam-splitter/combiner module outputs exactly on the 3Doptix grid, allowing an easy and accurate alignment. Due to the fact that all elements are exactly on the 3D grid, the three modules can easily be assembled together or can be separate on the optical table.
