In order to construct future optical interconnecting board providing ultra-broadband chip-to-chip signal transmission, integrated-optic configuration from two-dimensional array of surface emitting lasers to two-dimensional array of photodiodes was discussed with wavelength-division-multiplexing technique. TE0 guided mode was used for signal transmission while TE1 mode was used for input/output coupling of free-space waves to/from waveguide. Guided-mode-selective focusing grating coupler and different-guided-mode-coupling distributed Bragg reflector were integrated in thin-film waveguide to form free-space-wave add/drop multiplexer. Two-channel multi-/demultiplexing function was experimentally demonstrated for the first time with 5 nm wavelength spacing around 850 nm wavelength, although insertion loss and crosstalk noise were estimated to be not sufficient but $-30$ and $-5$ dB, respectively.
