Abstract
Multimode fibers are used extensively in many applications including optical illumination, sensing, imaging, and spectroscopy. Recently many optical MEMS applications reported the use of MM fiber for delivery of the optical beam to the MOEMS component to make use of its high throughput and thus higher power carrying capacity. In such applications, the spatial distribution and the spatial coherence of the output beam from the MM fiber affects greatly the performance especially if the beam is launched into an optical interferometer. In this work, we present a new model for the MM fiber output, in which the output beam is considered as a quasi-homogeneous shell source decomposed to its coherent elementary functions. Experimental results are obtained for multimode fibers with core/cladding dimensions of 62.5/125 μm, 200/220 μm and 400/440 μm and for different excitation conditions. The model shows very good agreement with the measured intensity distribution at different propagation distances.
