Abstract
Spatial mode-division-multiplexing is seen as paramount to overcoming the bandwidth limitations of single-mode fiber. In this letter, spatial-multiplexing of polarization-maintaining, elliptical-core fiber is proposed using asymmetric Y-junctions. Asymmetric Y-junctions also allow for straightforward wavelength-and polarization-multiplexing. Numerical beam propagation method simulations are used to demonstrate the functioning of a three-mode elliptical-core fiber data link, which could easily be extended to more modes. The multiplexing of multiple spatial modes could potentially see multifold increases in fiber capacity.
