Summary:
Several mode de-multiplexers base on LP mode (Linearly Polarized) have been proposed and demonstrated [1-3], however, LP mode based multiplexing, have required multi-in multi-out (MIMO) processing due to its difficulty of mode de-multiplexing caused by the mode degeneration and the mode crosstalk. In order to resolve this problem, spatial multiplexing transmission using a single dimensional spatial mode has been proposed [4-5]. We are studying a phase control type de-multiplexer using Rowland circle waveguide to de-multiplex singledimensional spatial mode [6]. In this work, we investigated the light focusing function of the Rowland circle waveguide for single dimensional spatial mode. The simulated result shows the possibility of de-multiplexing single dimensional spatial mode with this configuration.
