Abstract

Spatial reuse of optical frequencies in optical fibers is possible through a novel Spatial Domain Multiplexing (SDM) technique that enables simultaneous propagation of two or more spatially multiplexed channels of exactly the same wavelength by confining them to unique spatial locations inside the fiber. Spatial filtering techniques are employed at the output end to separate the individual optical channels. The SDM channels follow helical path inside the carrier fiber and do not interfere with each other. This paper presents electromagnetic wave based model to analyze two such co-propagating SDM channels and then compares the model predictions to experimental data. The comparison of attenuation and dispersion show a close match to prove that SDM technique can be used to enhance the bandwidth of optical fiber systems.
