We demonstrate a simple method for coupling from a laser diode bar to a single-mode fiber using a stubbed waveguide. The stubbed waveguide serves as a mode homogenizer that converts the rectangular multimode distribution of the emission of the laser diode bar into a circular beam with a smooth profile. Then the output beam is coupled to the lensed single-mode fiber. With this method, a laser diode bar operating at 795 nm is coupled into a 4 km single-mode silica fiber and the first order of stimulated Raman scattering of 100 mW in the fiber is observed.
