We enhanced the total transmission of light through a disordered waveguidewith spatially inhomogeneous scattering and loss by shaping the incidentwavefront of a laser beam. Using an on-chip tapered lead, we were able toaccess all input modes in the waveguide with a spatial light modulator. Theadaptive wavefront shaping resulted in selective coupling of input light tohigh transmission channels, which bypassed the regions of higher scattering andloss in the waveguide. The spatial inhomogeneity of scattering and loss led toredirecting of energy flux to optical paths with less scattering and loss tomaximize total energy transported through the system. This work demonstratedthe power of wavefront shaping in coherent control of light transport ininhomogeneous scattering media, which are common in real applications.
