Systems and methods for implementing a multimode splitting structure that divides a multimode wide waveguide into multiple narrower waveguides for photodetector connections in an optoelectronic system are disclosed. The optoelectronic system includes an optical filter, a multimode splitter, and a plurality of photodetector. The optical filter is communicatively coupled to a first waveguide to receive an optical signal and configured to demultiplex the optical signal onto a plurality of second waveguides based on different wavelengths. The multimode splitter is adapted to divide each of the plurality of second waveguides into a plurality of third waveguides. Each of the plurality of photodetector is adapted to be connected to each of the plurality of the third waveguide.

Multimode splitter for narrowing input width photodetector connections

Optical waveguides may include a substrate and a silicon based optical waveguide supported on the substrate. The silicon based optical waveguide may include a central ridge portion and a plurality of spaced apart wing portions connected through connecting portions. The number of wing portions may be greater than two. The central ridge portion may have a central ridge lateral width extent greater than a lateral width extent of at least one of the wing portions. Optical waveguides may include a substrate, a silicon based optical waveguide supported on the substrate, and a concentrator supported on the substrate and positioned within a lateral width extent of the silicon based optical waveguide and outside of a height extent of the silicon based optical waveguide. The optical waveguides may be included as part of an optical modulator.
