Abstract
A semiconductor device includes a plurality of intermediate waveguides. The plurality of intermediate waveguides are vertically disposed on top of one another, and vertically adjacent ones of the plurality of intermediate waveguides are laterally offset from each other. When viewed from the top, each of the plurality of intermediate waveguides essentially consists of a first portion and a second portion, the first portion has a first varying width that increases from a first end of the corresponding intermediate waveguide to a middle of the corresponding intermediate waveguide, and the second portion has a second varying width that decreases from the middle of the corresponding intermediate waveguide to a second end of the corresponding intermediate waveguide.
