By integrating a grating-based backward mode converter, asymmetric bidirectional couplers, and thermo-optic 2 \u00d7 2 switches, the proposed device enables direct and reconfigurable access to the TE\n                    <jats:sub>0<\/jats:sub>\n                    and TE\n                    <jats:sub>1<\/jats:sub>\n                    modes in a multimode bus waveguide without requiring complex intermediate mode processing. Experimental results show that the device successfully achieves selective add-drop operation for both modes. At 1550\u2009nm, all add-drop channels exhibit insertion losses below 1.7\u2009dB and modal crosstalk lower than \u221217.4\u2009dB. Broadband operation is experimentally demonstrated over the wavelength range of 1510\u20131600\u2009nm, where the insertion losses remain below 2\u2009dB, and the modal crosstalk is better than \u221215\u2009dB for all channels.
