1. A device, comprising:
a waveguide;
a light coupling material disposed adjacent to the waveguide and having a first surface and a second surface opposite to the first surface, wherein a height of the first surface is less than a height of the second surface, and the waveguide is disposed more adjacent to the first surface than to the second surface;
a light emitting element, wherein the light coupling material is between the light emitting element and the waveguide, the light emitting element has a lateral surface facing the second surface of the light coupling material, and a height of the lateral surface of the light emitting element is substantially equal to the height of the second surface of the light coupling material from a cross-sectional view perspective.
