Abstract: A device is provided. The device may be an optical device, a light coupling device, or a tunable light coupling device. The device includes a first portion, a lens, a light emitting element, and a waveguide. The first portion is disposed adjacent to a surface of a substrate and has a first side and a second side opposite to the first side. The light emitting element is disposed adjacent to the second side of the first portion. The lens is disposed adjacent to the first side of the first portion and between the light emitting element and the waveguide.
