Abstract
The present disclosure describes an optical system and method of operating the optical system. The optical system includes a substrate and first and second photonic integrated circuits. The first photonic integrated circuit is positioned on the substrate. The second photonic integrated circuit is positioned on the first photonic integrated circuit. The second photonic integrated circuit receives a first optical signal that includes a first mode and a second mode. The second photonic integrated circuit includes a polarization splitter rotator, a first demultiplexer, and a second demultiplexer. The polarization splitter rotator separates the first optical signal into a second optical with the first mode and a third optical signal with the first mode. The first and second demultiplexers separate the second and third optical signals into first and second pluralities of optical signals. The first and second pluralities of optical signals couple into the first photonic integrated circuit.
