摘要

While the simplest fiber optics are realized by transmission intensity modulations impressed on multimode fibers, great enhancements in sensitivity are achieved by interferometric or polarimetric methods with light propagated through single-mode fibers. In this paper we report preliminary experiments on retaining the sensitivity of interferometric and/or polarimetric measurements while using only multimode fiber components. The utility of success in this endeavor can be measured by greater experimental simplicity (light injection and alignment tolerances), by cost factors (cheaper fiber optics components), or by larger intensity transmission limits (which can be translated to higher time resolution for a given signal-to-noise ratio). 14 refs., 3 figs.
