We present the ultra-compact hybrid integration of a 1060-nm-band multi-wavelength vertical cavity surface emitting laser (VCSEL) array with a tapered hollow waveguide multiplexer. The design of the hollow waveguide multiplexer is presented based on ray optics. We show the potential of a 12-channel array VCSEL output multiplexed in a multi-mode fiber. The device length is as small as 200 mu m. The proposed hollow waveguide multiplexer would be useful for realizing compact wavelength division multiplexing (WDM) transceivers for optical interconnects.
