摘要： An optical component has a bottom part located in an opening defined by a surface, wherein a distance between a sidewall of the bottom part of the optical component and a sidewall of the opening is non-uniform in which a width of a first section of the opening or a first section of the bottom part of the optical component is narrower than a width of a second lower section of the opening or a width of a second lower section of the bottom part of the optical component; and an adhesive is located in the opening between sidewalls.

摘要： A number of beams that can be coupled into an optical fiber can be increased using emitted beams having greater divergence, thus providing increased beam power. Alternatively, with a fixed number of emitters, total optical power can be maintained with fewer beams in an output beam with a smaller numerical aperture.
