A paper by Chang-Seok Kim, Young-Geun Han, Jin U. Kang, Bernard Choi,
and J. Stuart Nelson, in issue 24 of volume 12 of Optics Express
describes the use of an electro-optic modulator inside a Sagnac loop
interferometer. So, apparently it can be done.
Since a Sagnac loop *is* an interferometer, of course, if you do use
anything inside the loop to modulate the intensity of the interfering
beam, you must be sure that you are not disturbing the phase of the beam
that you are modulating.
Other than these very simple and general comments, though, I do not have
sufficient expertise in this field to be of any _real_ help.
