Abstract
A focusing member and an optoelectronic device having the same are provided. The focusing member includes multiple levels of conductive plugs and multiple levels of conductive layers that together form an inversed half-boat shape. The optoelectronic device includes a bottom layer, an optical waveguide above the bottom layer, a dielectric layer covering the optical waveguide, and the above focusing member disposed at an edge of the optoelectronic device and located in the dielectric layer above the optical waveguide. A wider end of the inversed half-boat shape of the focusing member faces the outside of the optoelectronic device. The refractive indexes of the bottom layer and the dielectric layer are smaller than that of the optical waveguide.
