Methods, systems, and devices are disclosed for implementing a fiber-waveguide evanescent coupling. In one aspect, a device having integrated photonic components includes a substrate, a waveguide formed on the substrate to include a terminal waveguide portion that terminates at one side of the substrate, and a fiber including a fiber core and fiber cladding surrounding the fiber core, in which at least a portion of the fiber cladding is removed at or near a fiber terminal end to enable optical evanescent coupling via a side surface of the fiber core at the or near the fiber terminal end, the fiber core at the or near the fiber terminal end is placed over the one side of the substrate to be above and to overlap with the terminal waveguide portion of the waveguide to enable optical evanescent coupling via side surfaces of the fiber core and the waveguide. |
