A four-order asymmetric Y-junctions mode (de)multiplexer ((de)MUX) was theoretically proposed for highly integrated on-chip mode-division systems. The high-order mode in the stem waveguide of asymmetric Y-junctions is designed to be separated from the lower-order mode and evolve into the fundamental mode in the narrow arm. Through the widths optimization of branch arms by effective index matching and beam propagation method, the footprint of four-order mode (de)MUX was controlled to be 140×7.1μm2. The calculated excess loss and crosstalk were less than 0.3 dB and -18 dB within the operation wavelength range from 1460 to 1660 nm, respectively. This scheme may be expanded to higherorder modes (de)MUX design.
