Abstract: A waveguide includes a first layer and a second layer. The first layer comprises a material of a first refractive index. The second layer is surrounded by the first layer and comprises a material of a second refractive index greater than the first refractive index. The second layer comprises a main body, a first fork and a second fork. The main body has a first substantially constant thickness. The first fork is extended from the main body and has a first tapering end exposed by the first layer. The first fork has the first substantially constant thickness. The second fork is extended from the main body and has a second tapering end exposed by the first layer. The second fork has the first substantially constant thickness.

Abstract: An optical device package includes: (1) a waveguide, the waveguide including: a main body; and multiple forks, wherein each of the plurality of forks has a tapering end and is extended from the main body, and wherein each of the tapering ends of the forks includes a facet for receiving light; and (2) an optical fiber having a surface configured to output the light into the waveguide; wherein a lateral distance between the surface of the optical fiber and at least one of the facets is less than about 25 micrometers (μm).
