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

Semiconductor electro-optical modulators which receives an input optical signal and provides a modulated output optical signal based on an input electrical signal are disclosed. The semiconductor electro-optical modulator may comprise at least one electrical transmission line adapted to carry the input electrical signal and a semiconductor electro-optical phase shifter waveguide electrically coupled to the at least one electrical transmission line. An optical path length of the semiconductor electro-optical phase shifter waveguide between a modulation begin plane of the semiconductor electro-optical modulator and a modulation end plane of the semiconductor electro-optical modulator may be greater than an electrical path length of the electrical transmission line between the modulation begin plane of the semiconductor electro-optical modulator and the modulation end plane of the semiconductor electro-optical modulator.
