1. A structure comprising:
an edge coupler including a waveguide core having an end surface and a longitudinal axis, the end surface defining a first plane tilted in a first direction at a first acute angle relative to the longitudinal axis and tilted in a second direction at a second acute angle relative to the longitudinal axis, and the second direction different than the first direction; and
a dielectric layer having an interface with the end surface of the waveguide core and a surface that is tilted at a third acute angle relative to the longitudinal axis,
wherein the dielectric layer comprises a first material, and the waveguide core comprises a second material having a different refractive index than the first material.
