We demonstrate an efficient light coupler between a valley photonic crystal waveguide formed at a bearded interface and a wire waveguide. Numerically calculated coupling loss is less than 1 dB/coupler. We fabricated the couplers in a Si slab and experimentally observed a low coupling loss of 1.1 dB/coupler. These results will lay ground work for low-loss photonic circuits with topological waveguides.
