Spatial Single Dimensional Mode Based De-multiplexer Using Slab Waveguide

Abstract

This paper reports a single dimensional mode based multiplexer / de-multiplexer using the slab waveguide to realize high modes multiplexing and high integration in the non-MIMO (multi-in multi-out) multimode transmission system. A sufficient mode crosstalk of -20 dB was obtained by selecting suitable parameters of the spacing between the connecting positions of each arrayed waveguide D_i, the radius slab waveguide R₀ and lateral V-parameter.
