 The heterodyne module is designed to provide a fiber coupled heterodyne beat note formed by picking-off a small proportion of light from each of two laser beams. Light is coupled into a multi-mode fiber. A second output port can be used to overlap the two picked-off beams.  The light entering the module should be horizontally polarized for best results. The heterodyne module is designed to provide a fiber coupled heterodyne beat note formed by picking-off a small proportion of light from each of two laser beams.

 The procedure outlined above should work to align the module, but if difficulties are encountered another alignment procedure is possible with a fiber coupled laser such as the laser pens that are used to check fiber continuity and align light into fibers.  In this procedure, light should travel the reverse direction through the fiber so that the light is output into the module.  The beams should then be adjusted such that this reverse-coupled light overlaps well with the two laser beams entering the module.   The procedure outlined above should work to align the module, but if difficulties are encountered another alignment procedure is possible with a fiber coupled laser such as the laser pens that are used to check fiber continuity and align light into fibers.  In this procedure, light should travel the reverse direction through the fiber so that the light is output into the module.  The beams should then be adjusted such that this reverse-coupled light overlaps well with the two laser beams entering the module.
